Detailed step by step solutions to your Trigonometric Equations problems with our math solver and online calculator.
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
Note that \cos^2x-\sin^2x=\cos2x So your equation gives (\sin^2x-\cos^2x)(\sin^2x+\cos^2x) =(-\cos2x)(1)
This calculator can solve basic trigonometric equations such as: sin(x) = 21 or 2cos(− 43x) − 1 = 0. The calculator will find exact or approximate solutions on custom range. Solution can be expressed either in radians or degrees. Solve equation sin(2x) = 23 for 0 ≤ x ≤ 360∘. Find all solutions of the equation cos(23x) = − 22.
