Show that- please show actual steps because I don't understand
(cosA/1+sinA)+(1+sinA/cosA) simplifies to 2/cosA

The equation is most probably this:

$\frac{cos A}{1 + sin A} + \frac {1 + sin A}{cos A} = \frac {2}{cos A}$

How far have you progressed?

I don't think that is right because it doesn't equal 2/cosa, it only simplifies to it.

What you had written seemed ambiguous. So I latexed it correctly. How far have you simplified the expression?

Then I guess the question is "what in the world do you mean by simplifies"?
