WebNow, we have another trigonometric formula which is the double angle formula of the cosine function given by cos2x = 1 - 2sin^2x. Using this formula and interchanging the terms, we can write it as 2 sin^2x = 1 - cos2x ⇒ sin^2x = (1 - cos2x)/2. Hence the formula of sine square x using the cos2x formula is sin^2x = (1 - cos2x)/2. This formula ... WebThe first shows how we can express sin θ in terms of cos θ; the second shows how we can express cos θ in terms of sin θ.
