Question

tan (90°- 0) = cot (180° + theta ).​

Answer 1

Answer:

In trigonometrical ratios of angles (180° - θ) we will find the relation between all six trigonometrical ratios. Using the above proved results we will prove all six trigonometrical ratios of (180° - θ). Therefore, cot (180° - θ) = - cot θ
