Question

solve 1+cos2x/2 x 1 + cos2x/2?

Answer 1

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

Answer 2

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

Answer 3

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.
