InterviewSolution

1.	Find the principal and general solution of `cotx=-sqrt(3)`
Answer» 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)`
