Tan 2A=cot(A-15) Or, Tan 2A =Tan [90-(A-15)] Or,Tan2A=Tan(90+15-A) Or,Tan2A=Tan(105-A) This implies, 2A= Mar 17, 2018 ... what is tan2a if sina=1/2 · If sinA = 1/3 and cosA<0find the exact value of tan2A. answers icon · Please help with this one. · Hi, can someone ... ... }A + 2 \sin^{2}A \cos^{2}A cos4A+2sin2Acos2A. Prove 2 tan ⁡ 2 A / ( 1 + tan ⁡ 2 A ) = sin ⁡ 2 A 2\tan 2A/(1+\tan^{2}A) = \sin 2A 2tan2A/(1+tan2A)=sin2A Jun 10, 2023 ... We found that sin2a=−0.96 and tan2a≈3.43 given cosa=−0.6. This was determined using trigonometric identities and the values of sina and cosa. Detailed step by step solution for prove tan(2A)-tan(A)=tan(A)sec(2A) They are called this because they involve trigonometric functions of double angles, i.e. sin 2A, cos 2A and tan 2A. In order to master the techniques explained ... Mar 28, 2010 ... Prove 1+tan2A=sec2A.avi. 7.1K views · 15 years ago ...more. Prashant Gohil. 388. Subscribe. 50. Share. Save. Report. Comments2. Sep 3, 2021 ... Tan 2A - Tan A = Tan A [2/(1-Tan^2 A) -1] = Tan A [(1 + Tan^2 A)/(1 - Tan^2 A)] = Tan A [(Cos^2 A + Sin^2 A)/(Cos^2 A - Sin^2 A)] = Tan A ... Mar 10, 2025 ... We can square both sides to find tan2A+2+cot2A=36. This simplifies to tan2A+cot2A=34. Prove the following trigonometric identity: cot (45° -A) = tan 2A + sec 2A. Solution: LHS = cot (45° -A) = \dfrac{cot45°.cotA + 1}{cotA
