yes I am aware that y= sin(theta) and x= cos(theta)
and yes I drew my unit circle
so sin20 is in the first quadrant but I am not sure how to import images here, if possible
and cos70= sin 20, I figured that out a few days ago, however I am stuck on 3 and 4
Without a calculator, find all solutions w between 0 and 360, inclusive, providing diagrams that support your results.
1) cosW=sin20
2) sinW=cos(-10)
3) sinW< 0.5
4) 1<tanW
