alright so i need some help with these problems, and if you can let me know how you did them. that would be awesome.
1. Find sin(theta) when cos(theta) is -.53170 and theta is in quadrant 3.
2. Combine the parametric equations y=5cos(t) and x=3sin(t) into one equation relating y to x.
3. Solve for side a, b and angle B
