- In this video, I share with you steps for using Pythagorean identity and common denominator to prove the trigonometry identity sin^2 (x) - cos^2 (x) - tan^2 (x) = (2sin^2 (x) - 2sin^4 (x) - 1)/(1 - sin^2 (x)) @24x7MathTutor #trigonometry #trigonometryidentities #maths #mathematics #math #anilkumarmath #khanacademy #khanacademyeducation #simplifyexpressions #trigonometricequation #algebra #pythagorean #pythagoreanidentity #sinefunction #cosinefunction #tangentfunction
