Trigonometric equations having + - pattern

How to solve trigonometric equations by just looking at the form...



For e.g., proving $$cos A - sin A + dfrac {1}{cos A + sin A} - 1 = csc A + cot A$$



First of all I know the LHS is in basic T-ratio so I don't need to convert them but if I divide LHS by $cos A$ it changes to $tan A$ and $csc A$. How do I solve questions like these which have + - pattern?



Although I did it but I want to do some other way as well.

    Please reformat your equations with MathJax so that we know exactly what you're talking about in the equations (mainly the division)
