Question regarding limits to see if my procedure of getting the answer is

limit x-> 0

tan(x^2)

x

i know it's indeterminate so i need find another way

so i did the tan identity

cosx^2

sinx^2

x

cosx^2 1
*
sinx^2 x

cosx^2

sinx^3

i don't know what to do, but i know that it has to be 0. any ideas?
