Tan 90 theta
WebSolution : Draw a right angled triangle ABC right angled at B. Let \(\angle\) A = \(\theta\), then \(\angle\) C = 90 – \(\theta\) cot A = \(cot\theta\) = \(AB\over ... Webtan (90° + A) = -cot A The below figure shows the sign of trigonometric functions in different quadrants. Now, tan 180° can be written as: tan 180° = tan (90° + 90°) From the above figure, we can say that tan (90° + A) lies in the second quadrant, where tan is not positive. = – cot 90° = – (cos 90°/sin 90°) = – (0/1) = 0 Therefore, tan 180° = 0 Or
