Question

Intregrate root{1+cos2x}

Answer 1

Answer:

Step-by-step explanation:

we have √ ( 1 + cos 2x )

so ∫ ( 1 + cos 2x )

= ∫ 1 + ∫ cos 2x

= x + 1/2 sin2x + c

Answer 2

$\int \sqrt{1 + \cos(2x) } dx$

using trigonometry formula

1 + cos2x = 2sin^2x

$\int \sqrt{2} \sin(x) dx \\ - \sqrt{2} \cos(x) + c$

where c is constant
