Been working a little problem here for a while, the whole thing looks like this:
sin(x)/tan(x) + cos(x)tan(x)
I know the right side can be simplified to sin(x), but im not sure about the left. I put it into terms of cosine and sine, making it: sin(x)/sin(x)/cos(x)
My thought process here was to then multiply by the reciprocal, which would end with the sin(x)'s cancelling out and leaving just cos(x).
Can anyone verify this?
