Question

sin 45 degree + cot 30 degree + tan 45 degree / tan30 degree + sin30 degree

Answer 1

Answers: tan 45° = 1; cos 45° = 1/√2 or √2/2; sin 90° = 1; cos 30° = √3/2; sin 30° = 1/2; cos 90° = 0. 3 Find sin(π/4), cos(π/6), tan(π/3). 4 Find each of the following angles from the clues, assuming all the angles are between 0 and π/2 (0° and 90°) inclusive.
