Hi, my name is Mike. I'm a student of Cal State Fullerton. I have this problem with L'hospital rule:

the Problem: find values of a and b that satisfy the following

lim (sin x/x^3 + a + b/x^2) = 0

x->0

I tried to combined the whole equation into one using common denominator but it's doesn't seem right at all because I have 2 unknown variables.
