Solve 4sin2θ + 4cosθ - 5 0 for 0° ≤ θ 180°

WebEquations involving trigonometric functions of a variable are known as Trigonometric Equations. Example: cos 2 x + 5 cos x – 7 = 0 , sin 5x + 3 sin 2 x = 6 , etc. The solutions of these equations for a trigonometric function in variable x, where x lies in between 0 ≤ x ≤ 2π is called the principal solution. WebTo solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions.
