tan/1cot +cot/1tan =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 (1cot) and (1+tan) to avoid confusion.
It may help to change tan/(1cot)to the equivalent 1/(cot1), and change cot/(1tan) to 1/(tan1), and then rewrite the sum on the left with a common denominator. 
Factor the trinomial
c^2+5c+6
