simplify sqrt(1-cos(2x))

Solution

simplify

1 - cos (2 x)

Solution

2 sin (x)

Solution steps

1 - cos (2 x)

Simplify

1 - cos (2 x) : 2 sin^{2} (x)

= 2 sin^{2} (x)

Apply radical rule:

assuming

a \geq 0, b \geq 0

= 2 sin^{2} (x)

Apply radical rule:

assuming

a \geq 0

sin^{2} (x) = sin (x)
