$2\cos\left(x\right)+\sqrt{3}=0$

Learn how to solve trigonometric equations problems step by step online. Solve the trigonometric equation 2cos(x)+3^0.5=0. The square root of 3 is \sqrt{3}. We need to isolate the dependent variable x, we can do that by subtracting \sqrt{3} from both sides of the equation. Eliminate the 2 from the left side, multiplying both sides of the equation by the inverse of 2. The angles where the function \cos\left(x\right) is -\frac{\sqrt{3}}{2} are.
