Exploration of Sine and [b]Co[/b]sine of [b]co[/b]mplementary angles[br][br](Adapted from work by tohweeteck on GeogebraTube)

What is the complement of a 35 degree angle?[br]Click on Sin Theta[br]Click on Complementary angle[br]Click on Sin (90 - theta)[br]Click on Cos(90- theta)[br][br]Change theta to 25 degrees and look at the values[br][br]What conjecture can you make?[br][br]Do the same process with the cosine.
