Giải Phương Trình Cos 2x + Sin^2x + 2cosx + 1 = 0 - Nguyễn

sin(2x) + cos(2x) = 0 Divide each term in the equation by cos(2x)Solving Equations Involving a Single Trigonometric Function. When we are given equations that involve only one of the six trigonometric functions, their solutions involve using algebraic techniques and the unit circle (see Figure 2).We need to make several considerations when the equation involves trigonometric functions other than sine and cosine.Find the general solution to the equation sin(2x)-cos(2x)=0.
