WebTwo trigonometric formulas that includes cos^2x are cos2x formulas given by cos2x = cos^2x - sin^2x and cos2x = 2cos^2x - 1. Using these formulas, we have cos^2x = cos2x + sin^2x and cos^2x = (cos2x + 1)/2. Therefore, the formulas of cos^2x are: cos^2x = 1 - sin^2x ⇒ cos 2 x = 1 - sin 2 x cos^2x = cos2x + sin^2x ⇒ cos 2 x = cos2x + sin 2 xWeb26. 2 sin² x + 5 sin x +2 =0; 27.
