Now substitute 2φ = θ into … 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).

Webbtan^2 = sin^2+cos^2 = 1 << this we can agree on the solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still following then somehow it says therefore tan^2-1 = sec^2 so it replaces the entire first argument with sec^2, completely ignoring that 1 we were supposed to deduct from tan.
