Solve sin 2 X equal to cos 3 x for general solution

Answer» COS(π/2 - 2x) = cos3x

so

3x = 2nπ +- [π/2 - 2x]

Take + one TIME and solve for x then - one time and solve for x.

Ans. x = 1/5(2nπ + π /2) and (2nπ - π/2)

Godspeed!!

p.s. Don't INSTALL Quora for asking this kind of questions..

p.p.s. Quora is pretty cool for other stuffs!!
