wot curve, i mean like the limx->0 sinx/x = 1
kinda things yk. ik its simple lol but i just want a better grasp
in terms of proof you can view it geometrically via graph, or for a complete derivation iirc its about viewing the area of a sector, making an inequality with a triangle that can be formed from the chord to the centre and also another traingle that passes two points of said sector and branches out of the circle. then u cancel some yap u get sinx<=theta<=tanx and since this is the case u can div everyhting by sinx and u get 1<=theta<=1/cosx
Take lim where x->0 and u get 1<=theta<=1. using pinching theoremn, u get limx->0(x/sinx)=1

Omg I hate when they do this. We have a whole syllabus topic that we are being examined on, on friday for PDH, and we are being taught it all in a single hour lesson tomorrow morning. I'm so cooked.
