Solve a Trig Equation by Finding a Greatest Common Factor

WebExample 4: Solve for x:sin2 x sin x 2 0, 0d x 2S. Solution : Factor the quadratic expression on the left and set each factor to zero. sin2 x sin x 2 0 (sin x 1)(sin x 2) 0 sinx 1 0 or sinx 2 0 sinx 1 sinx 2 2 S x No solution. (Since the minimum value of sinx is -1, it cannot equal -2.) Answer: Example 5: Solve for x:tan2x 1, .
