Uppgift. Försök lösa ekvationen \sin(3x) = \cos(2x). Vilka svårigheter kan du förutse? En ledtråd finner du i figuren nedan.

Solve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Cos^2x-sin^2x = cos 2x. so cos 2x = 0. so 2x = pi/2 or 3pi/2 . 2x = 2npi + pi/2 and 2npi + 3pi/2.
