WebApr 15, 2015 · Solve the equation: f (x) = cos^2 x - sin^2 x - sin x = 0. Replace cos^2 x by (1 - sin^2 x) f (x) = 1 - sin^2 x - sin^2 x - sin x = 0. Call t = sin x Quadratic equation in t: f (t) = -2 t^2 - t + 1 = 0. Solve this quadratic equation. There are 2 real roots : t1 = -1 and t2 = 1/2. Solve the basic trig equation: t1 = sin x = -1 --> x = 3Pi/2 WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations.
Webf(x)=sin2x−cos2x On differentiating both sides w.r.t x, we get f(x)=cos2x×(2)−(−sin2x)×(2) f(x)=2(cos2x+sin2x) Put x= 6π Therefore, f(6π)=2(cos 3π+sin 3π) f(6π)=2(21+ 2 3) f(6π)=2( 21+ 3) f(6π)=1+ 3 Hence, the value is 1+ 3.
