or more complicated

$\displaystyle y =(4X+3)\frac{1}{1+e^{3X^3+2x^2+4X-2}}

$

I was able to get some help on finding the derivative in the Calculus section but have been unable to figure out how to simplify this equation.

Also, how do I calculate the square of an e^x equation:

$\displaystyle y = {(1+e^{3X-2})}^2

$
