Limits?

I understand limits, for the most part
these are some problems I'm still not sure about

1) lim 3 sin4x/sin3x
x->0

2) lim sinx/2x^2-x
x->0

3)lim sin^2x/x
x->0

Would appreciate help, thanks

    Ooh. That first one is quite crazy to prove algebraically. You have to expand that numerator twice and the denominator once. It uses the expansion on your flashcards.
