PLEASE HELP!
Show that:
(cosA/1+sinA)+(1+sinA/cosA) simplifies to 2/cosA
1. Put in sufficient brackets to make you question statement unambiguous.
2. Lets assume you mean: Simplify:
$\displaystyle \frac{\cos(A)}{1+\sin(a)}+\frac{1+\sin(A)}{\cos(A) }$
Put everything over a common denominator and simplify. The only trig involved is knowing that $\displaystyle (\sin(A))^2+(\cos(A))^2=1$
