simplify sqrt(49(1-sin^2(θ)))

simplify

49 (1 - sin^{2} (θ))

7 cos^{2} (θ)

Solution steps

49 (1 - sin^{2} (θ))

Apply radical rule:

assuming

a \geq 0, b \geq 0

= 49 - sin^{2} (θ) + 1

49 = 7

= 7 - sin^{2} (θ) + 1

Rewrite using trig identities

= 7 cos^{2} (θ)

cos (6 0^{\circ} + X)

cot (\frac{π}{2} - u)

4 - 4 cos^{2} (t)

- 2 + 2 sin (2 x - \frac{π}{2})

a^{2} - ((a sin (x)))^{2}
