RULES OF DIFFERENTIATION

Derivative of Sum

Examples

Find the derivative of each of the following

(a)    2x3 – 5x2 + 2

(b)    3x2 +

(c)    x3 + 2x2 + 1/x

Functions of a Function

Suppose we know that y is a function of u and the u itself is also a functions of x, how do we find the derivation of y with respect to x?

In other words, given y = f (u) and u = h(x)
