Hey choi105.

Please show us what you have tried. - Apr 15th 2013, 05:55 PMchoi105Re: Please help me how to solve this question.
sin x sec x - 3 sin x = 0

sin x 1/cos x - 3 sin x = 0

sin x - 3 sin x = cos x

then i not sure the step correct or not... - Apr 15th 2013, 06:45 PMchiroRe: Please help me how to solve this question.
Hint: Try thinking in terms of tan(x).
