"WebWe can determine the period of a cosine function by using the coefficient of the variable x. This coefficient is usually represented by the letter B. Therefore, the standard form of the cosine function is y = \sin (Bx) y = sin(B x). Using this form, we can obtain the following formula: \text {Period}=\frac {2\pi} { B } Period = ∣B∣2π " - Period of cosine squared

WebWe will determine the value of cos 120° using the cos2x identity. We know that cos2x = cos 2 x - sin 2 x and sin 60° = √3/2, cos 60° = 1/2. Since 2x = 120°, x = 60°. Therefore, we have. … WebTo arrive at the formulas of cos^2x, we will use various trigonometric formulas. The first formula that we will use is sin^2x + cos^2x = 1 (Pythagorean identity). Using this formula, subtract sin^2x from both sides of the equation, we have sin^2x + cos^2x -sin^2x = 1 -sin^2x which implies cos^2x = 1 - sin^2x.
