Web1 Oct 2016 · Trigonometry Trigonometric Identities and Equations Proving Identities 1 Answer George C. Oct 1, 2016 See explanation... Explanation: Starting from: cos2(x) + sin2(x) = 1 Divide both sides by cos2(x) to get: cos2(x) cos2(x) + sin2(x) cos2(x) = 1 cos2(x) which simplifies to: 1 + tan2(x) = sec2(x) Answer link WebProve that (cosecA-sinA) (secA-cosA)=1/tanA+cotA Solution Dear student, LHS = (cosecA – sinA). (secA – cosA) = (1/sinA - SinA). (1/cosA - cosA) = [ (1-Sin^2A)/SinA]. [ [1-cos^2A)/Cosa] = [cos^2A/SinA]. [Sin^2A/CosA] {cancelling equal terms on Nr and Dr We get} = cosA.SinA RHS = 1/ (tanA + cotA) = 1/ ( (SinA/CosA + CosA/SinA) td bank atrium way mt laurel nj

LHS = (Cosec A - Sin A) (Sec A - Cos A) = (1/sin A - Sin A) (1/cos A - cos A) = [ (1 - sin2 A)/sin A] [ ( 1 - cos2 A)/cos A] = [ (cos 2 A)/sin A] [sin 2 A/cos A] = sin A cos A RHS = 1 / (Tan A + Cot A) = 1 / (sin A/cos A + cos A/sin A) = 1 / [ (sin 2 A + cos 2 A)/sin A cos A] = 1 / [1/sin A cos A] = sin A cos A LHS = RHS Hence proved. td bank auburn
