$\huge \frac{ 1 }{\sin x+1 }- \frac{ 1 }{ sinx-1 } = \frac{ 2 }{ \cos^{2}x }$

2. burhan101 Group Title

$\huge \frac{ 1 }{ sinx+1 } - \frac{ 1 }{ sinx-1 } = \frac{ 2 }{ 1-\sin^2x }$

You're going to have to add the ones on the left before you see it.

4. burhan101 Group Title

what do you mean ? :S

5. wio Group Title

$\Large \frac{a}{b} - \frac{c}{d} = \frac{ad-cb}{bd}$

6. burhan101 Group Title

for the right side i get this : $\huge \frac{ (sinx-1)-(sinx+1) }{ 1-\sin^2x }$

7. irkiz Group Title

dont make your life hard combine the left hand side into 1 fraction first

8. irkiz Group Title

then multiply the denominators to remove the fraction

9. irkiz Group Title

then it would be extremely easy to solve

10. burhan101 Group Title

ohhh

11. irkiz Group Title

when u make the LHS into one fraction, u will get something like $\frac{ a }{ b }=\frac{ c }{ d }$ $ad = cb$
