Two angles with the same initial and terminal sides are called___________. They differ by a multiple of 2π or 360°.

• coterminal angles
• opposite angles
• complementary angles
• adjacent angles

Convert 130.3° to radians. Round to two decimal places if necessary.

What do we call the graph of the equation x²+y²=1?

If I am looking on the unit circle at a point (x,y), how else can we write that point?

Think in terms of Trig. Let "t" be the angle measure.
