Question

What is the first and second derivative of 3/(1+2(x^3)) ?
im tempted to do the quotient rule, but this looks weird to me...any advice would be greatly appreciated!!

Answer 1

let u=(1+2x^3)

then f= 3u^-1
f'= -3 *u^-2 *u'

but u'= 6x^2

so f'= -3*6x^2 /(1+2x^3)^2

Answer 2

In google type: calc101

When you see list of resultc click on:

Calc101com Automatic Calculus,Linear Algebra and Polynomials
When page be open clik option: derivatives

When this page be open in rectacangle type:

3/(1+2(x^3))

and click options DO IT

You will see solution step-by-step

By the way on this site you can practice any kind of derivation.
