simplify sqrt(4(1-sin^2(x)))

simplify

4 (1 - sin^{2} (x))

2 cos^{2} (x)

Solution steps

4 (1 - sin^{2} (x))

Apply radical rule:

assuming

a \geq 0, b \geq 0

= 4 - sin^{2} (x) + 1

4 = 2

= 2 - sin^{2} (x) + 1

Rewrite using trig identities

= 2 cos^{2} (x)

tan (2 x) cot (\frac{π}{5} - x)

cos (θ + π) - sin (π - θ)

36 - (6 sin (x))^{2}

tan (48 π + x)

sec^{2} (\frac{11}{45} π) d x
