Answer» Find the general solutions of the following equations:

(i) sin 2x=32

(ii) cos 3x=12

(iii) sin 9x=sin x

(iv) sin 2x=cos 3x

(v) tan x+cot 2x=0

(vi) tan 3x=cot x

(vii) tan 2x tan x=1

(viii) tan mx+cot nx=0

(ix) tan px=cot qx

(x) sin 2x+cos x=0

(xi) sin x=tan x

(xii) sin 3x+cos 2x=0
