1. ## Calculating Derivatives

I'm having trouble with how to approach these two problems:

1.) Calculate y'(0). $y'(x)=(-(e^x)y-1/y)/(e^x)-(x/y^2)$

2.) Calculate f'(x). $f(x)=6x^5(2x-1)^2(3x-1)$

I don't understand how to start each problem. Once I understand how to start them, I should be able to solve. I admit the first one makes me embarrassed. My head is just not thinking today. Thanks in advance.

This is just the case where x=0 so set x equal to 0 in the equation.

I think in the second one you will just have to multiply the whole thing out. then taking the derivative should be easy.

3. Man I knew number 1 was something really easy. I didn't post the entire problem in hopes I would figure out with help from here. I forgot that my professor gave us y(0)=3 which solves my problem.

Now for number 2.... I figured there would be an easier way than to multiply it out. Thanks for the help!
