if you get common denominators, it would make it possible to combine the two functions

And at the top you would get [2 x (1 + cos2x)] + [ 2x +1 (cos2x) ] all over [2x+1 (2)]

That's like (3/6) + (2/5). You would get common denominator by just multiplying the denominators. And when you multiply the bottom by a number, you have to multiply the top by the same number. |dw:1333340361869:dw|

And going back to your problem... I think you would be left with: 2x + cos2x + 4 cos 2x all divided by (4x+2)
