Prove cosA/1-tanA + sinA/1-cotA = sinA+cosA |
|
Answer» -step explanation:L.H.S. = cos A/1 – tanA + sin A/1 – cot A= cos A/1 – sin A/cos A + sin A/1 – cos A/sin A= cos A/(cos A – sin A)/COSA + sin A/(sin A – cos A)/sin A= COS2 A/cos A – SINA + sin2 A/sinA – cos A= cos2 A – sin2A/(cos A – sin A)= (cos A + sin A)(cos A – sin A)/(cos A – sin A)= cos A + sin A= R.H.S.Hence provedhope it is helpful MARK as BRAINLIST.. |
