Find the principal solutions of cosec x = 2 - Mathematics and Statistics
Find the principal solutions of cosec x = 2
cosec x = 2
∴ cosec x = `"cosec" (pi/6)` and cosec x = `"cosec" (pi - pi/6)`
= `"cosec" ((5pi)/6)`
such that `0 ≤ pi/6 < 2pi` and `0 ≤ (5pi)/6 < 2pi`
∴ The required principal solutions are x = `pi/6` and x = `(5pi)/6`.
