Prove Sin A/1+cos A=1-cos A/ Sin A |
|
Answer» Answer: hey... buddy here is your answer... mark it as BRAINLIST..... ... hope this helps you... ..To PROVE, ....sinA/1+cosA=1-cosA/sinA L.H.S=sinA/1+cosA rationalise the denominator of the L. H. s.. sinA×(1—cosA)/(1+cosA)×(1—cosA) using the property (a+b)(a–b) =a²–b² sinA(1—cosA) /(1)²—(COS)² sinA(1—cosA) /(1—cos²A) using the property (1–cos²A) =sin²A sinA(1—cos A) /Sin²A SinA(1—cosA) /sinA×sinA (1—cosA) /sinA=L.H.S....... proved... ... .....follow me GUYS.. |
