tan/1-cot +cot/1-tan =1+sec cosec

  • math - ,

    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.

  • math - ,

    Factor the trinomial
    c^2+5c+6
