Question

How do you find the value of cot 0?​

Answer 1

Step-by-step explanation:

Solution

We know that

cot x=cos x / sin x

Hence

cot 0=cos 0 / sin 0

Let us substitute the values of cos 0 and sin 0 in the above equation

The values are

cos0=1,sin0=0,

Therefore,

cot 0=1/0

cot 0 = ∞

This implies the fact that cot x doesn’t exist for x=nπ.
