Fullscreen

( begin{aligned} frac{cos A}{1-tan A}+frac{sin ^{2} A}{sin A-cos A} &=frac{cos A}{1-sin A}+frac{sin ^{2} A}{sin A-cos A} =& frac{cos ^{2} A}{cos A-sin A}-frac{sin ^{2} A}{cos A-sin A} =& frac{cos ^{2} A-sin ^{2} A}{cos A-sin A} =&(cos A-sin A)(cos A+sin A) & cos A-sin A =& cos A+sin A =& R H S text { Heres proved. } end{aligned} )
