Question

find the principal and general solution of the following equations :

cosec x = -2

Answer 1

$cosec \: \theta \: = - 2 \: or \: \: sin \theta \: = \frac{ - 1}{2}$


sin30° = 1 / 2 or sin (-30°) = - sin30° = -1/2


principal value of x = -30° = -π / 6


$general value of x = nπ + (-1)^n \alpha$


nπ + (-1)^ n ( - π / 6 )


= nπ - (-1) ^ n ( π / 6)
