uses differentiation rules and formulas. One need to substitute the values only and it helps in finding the

result will automatically come out.

This tool is very effective and also helps in finding the solutions of typical problems even involving higher

exponents. It also helps in evaluating the derivatives of trigonometric functions involving different variables.

This can be understood by the following examples:-

Find the derivative of the below mentioned function:-

a) x+8

Let f (x) = x+8

Now here we have to find the d/dx f(x).

Here, f (x) = x+8.

Therefore,

d/dx f(x) = d/dx (x+8)

= d/dx(x) + d/dx (8)

= dx/dx + 0 (because derivative of constant function

is 0).

= 1.

Find the derivative of the below mentioned function:-

a) x

Let f (x) = x

Now here we have to find the d/dx f(x).

Here, f (x) = x

Therefore,

d/dx f(x) = d/dx (x

= d/dx(x

= dx

Zero)

= 2x+1+0 (because d/dx (x

= 2x+1.
