Q.No.5 Find the general solution of the equation cot 0 = 0)​

Answer 1

$\theta = n\pi$

Explanation:

$Given, \: \: cot \theta = 0 \\ or, \: \: \: \: \: \: \: \: \: \: \: tan \theta = \infty \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: tan\theta = tan0 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \theta = 0 \\ we \: \: know \: \: that \: \: \boxed{general \: \: solution \: \: for \: \: tan \theta \: = n\pi + \theta} \\Therefore , \: \:the \: \: general \: \: solution \: \: is \: \\ \: \: \: \theta \: = n\pi + 0 \\ = n\pi$
