 lhs \\ \frac{tan}{1 - cot}  +  \frac{cot}{1 - tan}  \\  \frac{ \frac{sin}{cos} }{ \frac{sin - cos} {sin} }  +  \frac{ \frac{cos}{sin} }{ \frac{cos - sin}{cos} }  \\  \frac{ {sin}^{2} }{cos( sin- cos)}  +  \frac{ {cos}^{2} }{sin(cos - sin)}  \\ \frac{ {sin}^{2} }{cos( sin- cos)}   -   \frac{ {cos}^{2} }{sin(sin - cos)}   \\   \frac{ {sin}^{3} \:   -   {cos}^{3}  }{sin \times cos(sin - \: cos)}  \\  \frac{(sin \:  - cos)( {sin}^{2} +  {cos}^{2} + sin \times cos  )}{ sin \times cos( sin-cos )} \\  \frac{1 + sin \times cos}{sin \times cos \: }  = 1 + cosec  \times  sec

rhs \\ 1 + tan + cot \\ 1 +  \frac{sin}{cos}  +  \frac{cos}{sin}  \\  \frac{sin \times cos +  {sin}^{2}  +  {cos}^{2} }{sin \times cos \: }  \\  \frac{sin \times cos \: + 1 }{sin \times cos \:}   = 1 + cosec \times sec
