Need help about latex

I am unable to use latex. When I copy the code from daum text editor the code doesn't get formatted even though I wrap it in $ ... $.Why the following code doesn't get formatted , I copied it from daum editor .

$4\times \frac { a+b }{ a-b } { { \sin ^{ 2 } (\alpha -\beta ){ + } } }\frac { (b+c) }{ (b-c) } \sin ^{ 2 } (\beta -\gamma )+\frac { (c+a) }{ (c-a) } \sin ^{ 2 } (\gamma -\alpha ){ + }4$

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

For whatever reason, when you type in \(, you have an extra space between the \ and the (, which is why it doesn't get interpreted accordingly.

I've removed the space in your code, and the equation displays perfectly.

Sir why this code doesn't get formatted $\cos { 5\theta } $ .I would request you not to format it but tell the fault in the code.

As I stated, the way that you're typing it up (possibly if you're copying it), there is an (invisible) space between your \ and your (, which is why it doesn't recognize it accordingly.

If you were to edit your comment and remove the space, then it will display accordingly.
