How to deal with trig functions in limits? lim as x ->0 sin (x)/x

look in any text on calc and you will see the proof that \[\lim_{x\to 0}\frac{\sin(x)}{x}=1\] usually by something called the squeeze theorem later this will be obvious, but at the beginning that is what you have to do

You mean whenever we see trig functions in limits then we suppose to always use squeeze theorem? and please guide me, I am not good at trigonometry. If you could suggest me any tutorial on trig functions which used in calculus please tell me. I am not understanding limits. I tried different websites + khanacademy but it is not so much helpful.

it can also be done by the tabular number thingy
