For both questions i have to find dy/dx(adsbygoogle = window.adsbygoogle || []).push({});

1. y=x^5e^-3x

I got (5x^4 e^-3x) + (x^5 (-3xe^-3x-1))

some how that doesn't look right to me. not too sure...

2.

1-e^-x

y= --------

1+e^2x

My answer was:

(e^-x) - (1-e^-x) (2xe^2x-1)

y'= -----------------------------

1+e^2x

Thanks for your help! It's much appreciated!
