Hence, the equation with R unspecified is the general equation for the circle. Usually, the unknowns are denoted by letters at the end of the alphabet, x , y , z , w , The process of finding the solutions, or, in case of parameters, expressing the unknowns in terms of the parameters, is called solving the equation. Such expressions of the solutions in terms of the parameters are also called solutions.

A system of equations is a set of simultaneous equations , usually in several unknowns for which the common solutions are sought. Thus, a solution to the system is a set of values for each of the unknowns, which together form a solution to each equation in the system. For example, the system. An identity is an equation that is true for all possible values of the variable s it contains. Many identities are known in algebra and calculus. In the process of solving an equation, an identity is often used to simplify an equation, making it more easily solvable.

In algebra, an example of an identity is the difference of two squares :. Trigonometry is an area where many identities exist; these are useful in manipulating or solving trigonometric equations.

Two of many that involve the sine and cosine functions are:. Two equations or two systems of equations are equivalent , if they have the same set of solutions. The following operations transform an equation or a system of equations into an equivalent one � provided that the operations are meaningful for the expressions they are applied to:.

If some function is applied to both sides of an equation, the resulting equation has the solutions of the initial equation among its solutions, but may have further solutions called extraneous solutions. Thus, caution must be exercised when applying such a transformation to an equation.

The above transformations are the basis of most elementary methods for equation solving , as well as some less elementary one, like Gaussian elimination. In general, an algebraic equation or polynomial equation is an equation of the form. An algebraic Mathematics Class 10 Cbse Syllabus And Pdf equation is univariate if it involves only one variable. On the other hand, a polynomial equation may involve several variables, in which case it is called multivariate multiple variables, x, y, z, etc.

The term polynomial equation is usually preferred to algebraic equation. Some but not all polynomial equations with rational coefficients have a solution that is an algebraic expression , with a finite number of operations involving just those coefficients i. This can be done for all such equations of degree one, two, three, or four; but for equations of degree five or more, it can be solved for some equations but, as the Abel�Ruffini theorem demonstrates, not for all.

A large amount of research has been devoted to compute efficiently accurate approximations of the real or complex solutions of a univariate algebraic equation see Root finding of polynomials and of the common solutions of several multivariate polynomial equations see System of polynomial equations. A system of linear equations or linear system is a collection of linear equations involving the same set of variables.

A solution to a linear system is an assignment of numbers to the variables such that all the equations are simultaneously satisfied. A solution to the system above is given by. The word " system " indicates that the equations are to be considered collectively, rather than individually. In mathematics, the theory of linear systems is the basis and a fundamental part of linear algebra , a subject which is used in most parts of modern mathematics.

Computational algorithms for finding the solutions are an important part of numerical linear algebra , and play a prominent role in physics , engineering , chemistry , computer science , and economics. A system of non-linear equations can often be approximated by a linear system see linearization , a helpful technique when making a mathematical model or computer simulation of a relatively complex system. In Euclidean geometry , it is possible to associate a set of coordinates to each point in space, for example by an orthogonal grid.

This method allows one to characterize geometric figures by equations. In other words, in space, all conics are defined as the solution set of an equation Mathematics Equations And Formulas Pdf 36 of a plane and of the equation of a cone just given. This formalism allows one to determine the positions and the properties of the focuses of a conic. The use of equations allows one to call on a large area of mathematics to solve geometric questions. The Cartesian coordinate system transforms a geometric problem into an analysis problem, once the figures are transformed into equations; thus the name analytic geometry.

This point of view, outlined by Descartes , enriches and modifies the type of geometry conceived of by the ancient Greek mathematicians. Currently, analytic geometry designates an active branch of mathematics. Although it still uses equations to characterize figures, it also uses other sophisticated techniques such as functional analysis and linear algebra.

A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates , which are the signed distances from the point to two fixed perpendicular directed lines, that are marked using the same unit of length.

One can use the same principle to Mathematics Equations And Formulas Pdf Template specify the position of any point in three- dimensional space by the use of three Cartesian coordinates, which are the signed distances to three mutually perpendicular planes or, equivalently, by its perpendicular projection onto three mutually perpendicular lines. Using the Cartesian coordinate system, geometric shapes such as curves can be described by Cartesian equations : algebraic equations involving the coordinates of the points lying on the shape.

A parametric equation for a curve expresses the coordinates of the points of the curve as functions of a variable , called a parameter. Together, these equations are called a parametric representation of the curve.

The notion of parametric equation has been generalized to surfaces , manifolds and algebraic varieties of higher dimension , with the number of parameters being equal to the dimension of the manifold or variety, and the number of equations being equal to the dimension of the space in which the manifold or variety is considered for curves the dimension is one and one parameter is used, for surfaces dimension two and two parameters, etc.

A Diophantine equation is a polynomial equation in two or more unknowns for which only the integer solutions are sought an integer solution is a solution such that all the unknowns take integer values.

A linear Diophantine equation is an equation between two sums of monomials of degree zero or one. An exponential Diophantine equation is one for which exponents of the terms of the equation can be unknowns.

Diophantine problems have fewer equations than unknown variables and involve finding integers that work correctly for all equations. In more technical language, they define an algebraic curve , algebraic surface , or more general object, and ask about the lattice points on it. The word Diophantine refers to the Hellenistic mathematician of the 3rd century, Diophantus of Alexandria , who made a study of such equations and was one of the first mathematicians to introduce symbolism into algebra.

The mathematical study of Diophantine problems that Diophantus initiated is now called Diophantine analysis. An algebraic number is a number that is a solution of a non-zero polynomial equation in one variable with rational coefficients or equivalently � by clearing denominators � with integer coefficients. Almost all real and complex numbers are transcendental.

Algebraic geometry is a branch of mathematics , classically studying solutions of polynomial equations. Modern algebraic geometry is based on more abstract techniques of abstract algebra , especially commutative algebra , with the language and the problems of geometry. The fundamental objects of study in algebraic geometry are algebraic varieties , which are geometric manifestations of solutions of systems of polynomial equations. Examples of the most studied classes of algebraic varieties are: plane algebraic curves , which include lines , circles , parabolas , ellipses , hyperbolas , cubic curves like elliptic curves and quartic curves like lemniscates , and Cassini ovals.

A point of the plane belongs to an algebraic curve if its coordinates satisfy a given polynomial equation. Basic questions involve the study of the points of special interest like the singular points , the inflection points and the points at infinity.

More advanced questions involve the topology of the curve and relations between the curves given by different equations. A differential equation is a mathematical equation that relates some function with its derivatives.

In applications, the functions usually represent physical quantities, the derivatives represent their rates of change, and the equation defines a relationship between the two. Because such relations are extremely common, differential equations play a prominent role in many disciplines including physics , engineering , economics , and biology.

In pure mathematics , differential equations are studied from several different perspectives, mostly concerned with their solutions � the set of functions that satisfy the equation. Only the simplest differential equations are solvable by explicit formulas; however, some properties of solutions of a given differential equation may be determined without finding their exact form.

If a self-contained formula for the solution is not available, the solution may be numerically approximated using computers.

The theory of dynamical systems puts emphasis on qualitative analysis of systems described by differential equations, while many numerical methods have been developed to determine solutions with a given degree of accuracy.
