In these problems you have to find the sine and cosine of the angle using
the sum formulas. The angle is between 0 and 90 degrees.
Not so basic sin/cos
Once again, you have to find the sine and cosine of the angle. But this
time the angle is between 0 and 360 degrees and you choose between
degrees or radians.
Find the angle
You are given the sine and cosine and you have to figure out what the
angle is in degrees which is between 0 and 360.
Here are some geometry problems where you have to know trig. The
Pythagorean theorem might come in handy too.
