Web6 dec. 2015 · 1 Answer mason m Dec 6, 2015 The Pythagorean identity states that sin2θ + cos2θ = 1. We can rearrange the identity to see that cos2θ = 1 − sin2θ. If we know that cos2θ = 1 − sin2θ, we can replace cos2θ with 1 − sin2θ in the expression cos2θ − sin2θ. cos2θ −sin2θ = (1−sin2θ)−sin2θ Combine like terms to see that: cos2θ −sin2θ = 1 − … Web`4sinthetasin2thetasin4theta=sin3theta` `4sintheta*sin2theta*sin4theta-(3sintheta-4sin^3theta)=0` `sintheta(4sin2theta*sin4theta-3+4sin^2theta)=0`
