Sin 2 theta + cos theta

Webb20 feb. 2024 · cos (2x) has a lot of equivalent ways it can be written, but a convenient way for us would involve only sines since that makes the equation a lot easier to work with. One of the identities for cos 2x is cos 2x = 1 - 2 sin 2 (x). This means an equivalent way of writing our problem is: 1 - 2sin 2 x = sin (x).
