1. simple question

can anybody solve this question?
it just a simple question but i forgot because i left math behind for a long time..

simplify cos^2(x)/(1-sinx)

2. Is the sin(x) in the denominator supposed to be squared or not? Just wondering. It's not now as I see it.

3. (1+sin x)

just write cos^2x=(1-sin^2 x)

no.. not to be squared

simplify cos^2(x)/(1-sinx)

$\displaystyle \frac{cos^2x}{1-sinx}$

$\displaystyle =\frac{(1-sin^2x)}{1-sinx}$

$\displaystyle =\frac{(1+sinx)(1-sinx)}{1-sinx}$

What is left ?

$\displaystyle \frac{cos^2x}{1-sinx}$
$\displaystyle =\frac{(1-sin^2x)}{1-sinx}$
$\displaystyle =\frac{(1+sinx)(1-sinx)}{1-sinx}$
