Question

find the limit of sin^2x/4x as x approaches pi/6

Answer 1

Just plug it in.

Answer 2

\[\large \lim_{x \rightarrow \frac{\pi}6}\frac{\sin^2 x}{4x}\]
if you notice, the only place for this function to be undefined is when the denominator is 0; the only case for this is x=0; other than that... you can just plug it in

Answer 3

Factor out of 1/4.
then take the limit of the numerator and denominator separately.

Answer 4

I would prefer that you post your work in here.
