Trignometry

[Master7731]

1. The problem statement, all variables and given/known data

What are the other Trignometry Rules/properties/common equations?



3. The attempt at a solution

cos2 theta + sin2 theta = 1
1 + tan2 theta = sec2 theta
1 + cot2 theta = csc2 theta
2sin theta = 2cos theta sin theta
