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
