## Homework Statement

Find

limit ...(1-cos(2x^2)) / (1-cos(3x^2))

x->0

**2. The attempt at a solution**

since the above gave me 0/0, I used l'Hopital method..

then i got

(4x)sin(2x^2) / (6x)(sin3x^2)

which gives me 0/0 again..

so I kept on using l'Hopital.. but it seemed on going forever

is there other way to solve this..?

thank you in advance
