Sine and Cosine of Complementary angles
- Susan Socha
Exploration of Sine and Cosine of complementary angles (Adapted from work by tohweeteck on GeogebraTube)
What is the complement of a 35 degree angle? Click on Sin Theta Click on Complementary angle Click on Sin (90 - theta) Click on Cos(90- theta) Change theta to 25 degrees and look at the values What conjecture can you make? Do the same process with the cosine.
