Formula expression equation identity
WebIdentity I: (a + b) 2 = a 2 + 2ab + b 2. Identity II: (a – b) 2 = a 2 – 2ab + b 2. Identity III: a 2 – b 2 = (a + b)(a – b) Identity IV: (x + a)(x + b) = x 2 + (a + b) x + ab. Identity V: (a + b + c) 2 = a 2 + b 2 + c 2 + 2ab + 2bc + 2ca. … WebThe identity 1 + cot2θ = csc2θ is found by rewriting the left side of the equation in terms of sine and cosine. Prove: 1 + cot2θ = csc2θ 1 + cot2θ = (1 + cos2θ sin2θ) Rewrite the left side. = (sin2θ sin2θ) + (cos2θ sin2θ) Write both terms with the common denominator. = sin2θ + cos2θ sin2θ = 1 sin2θ = csc2θ
