Question

what is the derivative of (e^2x)/[(x^2)+1]?

Answer 1

just apply quotient rule and chain rule

Answer 2

Take u=e^2x and v=(x^2 +1)
and apply u/v rule for differentiation

Answer 3

using the product rule and chain rule,it is
{2(e^2x)/([x^2] +1)} - {2x(e^2x)/[([x^2]+1)]^2}
u can simplify a little more
