tan/1-cot +cot/1-tan =1+sec cosec
The proper symbol used for cosecant is csc.
Please use parentheses where needed.
Is <1+sec cosec> supposed to represent
(1+ sec)*csc or , 1 + (sec*csc)> ?
You should also have used parentheses around (1-cot) and (1+tan) to avoid confusion.
It may help to change tan/(1-cot)to the equivalent 1/(cot-1), and change cot/(1-tan) to 1/(tan-1), and then rewrite the sum on the left with a common denominator.
Factor the trinomial
