# Thread: Should be easy Limit of a function

1. ## Should be easy Limit of a function

Hey, I can't seen to figure out the limit of this function:

Lim (e^x)((sin10x)/x))
x->0

I know i can break it up as the limir of e^x and the limit of ((sin10x)/x), and i know as x-> e^x will become 1, but it's the ((sin10x)/x) section which is confusing me. Obviously I need to change it so that x is not in the denominator, but I'm not sure how to go about that

Any ideas?

remember, $\lim_{x \to 0} \frac {\sin x}x = 1$

you have $\lim_{x \to 0} \frac {\sin 10x}x$

how can you write that in such a way as to find the limit?
