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

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

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

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.
