Even function
A function f : A B is said to be an even function if f(x) = f(-x) for all x A. The domain and range of f depends on the definition of the function. Examples of even function are y = cosx, y = x 2 , y = secx A polynomial with only even powers of x is an even ..

Derivative of a Function of a Function - So far, we know how to differentiate functions like sin x and x 3 - 5. But how do we differentiate a function of a function? That is how can we differentiate sin (x 3 - 5)?So far, we know how to differentiate..

The differentiation of function of a function is known as 'chain rule'. The chain rule is probably the most widely used differentiation rule in mathematics. If y is a differentiable function of u and u is a differentiable function of x, then the d..
Trigonometric functions
Trigonometric functions are sinx, cosx, tanx, etc. The graph of these functions have been done in class X..
Derivative of a Function
Derivative of a Function - So far we have discussed the derivative of a function f(x) at a point 'a' which is in the domain of f. Suppose we want to find the derivative of the same function at a different point 'b', then we have to compute the derivative by repeating t..
Monotonic Function
A function is said to be monotonic if it is either increasing or decreasing but not both in a given interval. Consider the function The given function is increasing function on R. Therefore it is a monotonic function in [0,1]. It has its minimum ..

A real valued function f : A to B or simply a real function 'f ' is a rule which associates to each possible real number x A, a unique real number f(x) B, when A and B are subsets of R, the set of real numbers. In other words, functions whose domain and co-domain are ..

Tutor Vista perceived the math apps well and I enjoyed getting to work with Tutor Vista - Savannah
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
I really liked Tutor Vista, I am confident I will get an A+ in my math test now, My sincere thanks to all the tutors -George
