G.SRT.7 Trig complements

This applet is designed to help you discover the relationships between trig functions and complementary angles. You should know what complementary angles are and the six basic trig functions.
What do you notice about the sin of an angle and the cos of its compliment? What happens if you move point c and change the angles? What about the other trig functions, tan, cot, sec, and csc? Do they have the same relationships with complementary angles?
