We thus observe, without actually solving the quadratic equation (a) We can find the value of every symmetric function involving the roots of the equation in terms of the coefficients of the equation. (b) We can find a quadratic equation whose roots are any one of the following ..

The mathematical concept of a function expresses the intuitive idea of deterministic dependence between two quantities, one of which is viewed as primary (the independent variable, argument of the function, or its "input") and the other as secondary (the value of the ..

(1) Let the given function be f (x) on the real number line R. (2) Differentiate the function f(x) with respect to x and equate it to zero i.e., put f '(x) = 0. Solve for x. These values of x which satisfy f '(x) = 0 are called Critical values of the function..

Any relation on A x B in which (i) no two second elements have a common first element and (ii) every first element has a corresponding second element is called a function..

The nervous system carries out the following functions i) It perceives the changes around us through our senses. ii) It controls and coordinates all the activities of the muscles in response to the changes outside. iii) It also maintains the internal environment of the body by coordinati..

A function is a relation on A x B is which (i) no two second elements have a common first element. (ii) every first element has a corresponding second element. Every function is either one-one onto or one-one into or many-one onto or many-one into...
