Find the value of the trigonometric function $$cot=(-\dfrac{15\pi}{4})$$

Asked by Pragya Singh | 1 year ago |  66

#### 1 Answer

##### Solution :-

We know that the values of cotx repeat after an interval of π or 180° .Therefore we can write,

$$cot=(-\dfrac{15\pi}{4})$$

$$cot=(-\dfrac{15\pi}{4}+4\pi)$$

$$cot=(\dfrac{\pi}{4})=1$$
