## Homework Statement

evaluate the limit as x goes to 0 of:

tan(4x^2)^2/(3x^4)

(thats suppose to say the tangent squared of 4 x squared all over 3 x to the 4th)

## Homework Equations

n/a

## The Attempt at a Solution

the only trig limit stuff i know is the limit to 0 of sinx / x = 1

and

limit to 0 of (1-cos x)/x = 0

is there a tangant one i should know? what about tangant squared? i also considered changing it to sin squared over cos squared but i dont know what i could do that with.

if anyone could give me a hint to get me started, i would appreciate it. thanks.
