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

c^2+5c+6
