WebMar 27, 2024 · Example 3.4.2.4. Prove the power reducing identity for sine. sin2x = 1 − cos2x 2. Solution. Using the double angle identity for cosine: cos2x = cos2x − sin2x cos2x = (1 − sin2x) − sin2x cos2x = 1 − 2sin2x. This expression is an equivalent expression to the double angle identity and is often considered an alternate form. WebHow do you use the fundamental identities to prove other identities? Divide the fundamental identity sin^2x + cos^2x = 1 by sin^2x or cos^2x to derive the other two: sin^2x/sin^2x + cos^2x/sin^2x = 1/sin^2x 1 + cot^2x = csc^2x sin^2x/cos^2x + cos^2x/cos^2x = 1/cos^2x tan^2x + 1 = sec^2x Kevin B. · 1 · Feb 22 2015 Questions
