Find the principal and general solution of `cotx=-sqrt(3)`

Explanation

Here, `cotx = -sqrt3`

We know, `cot(pi/6) = sqrt3` and cot x is negative in 2nd and 4th quadrant.

So, principal solution will be` (pi-pi/6)` and `(2pi-pi/6)`

Principle solution `x = (5pi)/6 and (11pi)/6`

General solution,`x = (npi-pi/6)`
