WebAboutTranscript. The Pythagorean identity tells us that no matter what the value of θ is, sin²θ+cos²θ is equal to 1. This follows from the Pythagorean theorem, which is why it's … WebAlternatively, we can use the double angle formulacos⁡2A≡1−2sin2⁡A{\displaystyle \cos 2A\equiv 1-2\sin ^{2}A}. By letting θ=2A{\displaystyle \theta =2A}, we get that …
