1. ## I need help

I need help on this problem.. i think its suppose to be simple but i don't know how to get the answer.

the problem is:
solve the initial-value problem 2t^2y''+3ty'-y=0; y(1)=2,y'(1)=1

thank you

thank you
in your lecture notes look for "Euler differential equation." if you have no lecture notes, then Google it.

Off topic, but Chris, your avatar is hilarious!

5. hmm if i did it that way.. why was i given y(1)=2,y'(1)=1????

What you usually find first when you solve a differential equation is the general solution (with arbitrary constants). The initial conditions are given so you can find the constants $\displaystyle c_1$ and $\displaystyle c_2$ from the general solution.
