WebbViewed 4k times. 1. Simplify the expression by using a Double-Angle Formula or a Half-Angle Formula. (a) cos 2 ( θ 2) − sin 2 ( θ 2) (b) 2 sin ( θ 2) cos ( θ 2) This is what I got: ( … WebbDouble angle identities are trigonometric identities that are used when we have a trigonometric function that has an input that is equal to twice a given angle. For example, we can use these identities to solve \sin (2\theta) sin(2θ). In this way, if we have the value of θ and we have to find \sin (2 \theta) sin(2θ), we can use this identity ... dvd creating software for windows 10
