WebThrough this formula, you can know that 2x•2=4x,Next,we can turn cos4x into 2cos2x^2–1.This formula is 2cos2x^2–1–2cos2x=3.2cos2x^2–2cos2x-4=0.cos2x^2 … WebJan 8, 2024 · Then $$\cos y = \sin y$$ First note that no solution to $\cos y =0$ solves this equation, so division throughout by $\cos y$ is allowed. You get $\tan y = 1$. At this point, you should be able to continue. Remember the periodicity of the tangent function (careful, the period is not $2\pi$) and don't forget to reverse the original substitution. ra 5163
