Question

• Explain in your words why this relationship of sine and cosine holds for complementary angles.

Answer 1

In general, the sine of any angle is equal to the cosine of the complementary angle. The cosine of any angle is equal to the sine of its complementary angle. For any angle A, these equations hold true:

Sin A = Cos (90 - A)

Cos A = Sin (90 - A)
