    1. Put in sufficient brackets to make you question statement unambiguous.

    2. Lets assume you mean: Simplify:

    \frac{\cos(A)}{1+\sin(a)}+\frac{1+\sin(A)}{\cos(A)  }

    Put everything over a common denominator and simplify. The only trig involved is knowing that (\sin(A))^2+(\cos(A))^2=1
