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

simplify

1 - sin^{2} (x) x

x cos (x)

Solution steps

1 - sin^{2} (x) x

Use the Pythagorean identity:

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

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

= x cos^{2} (x)

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

= x cos (x)

cos (377 t + 377 t + π)

cos (x - \frac{8 π}{3})

cos (2 π - a)

2 sin (x + 4 5^{\circ})

2 cos (πn)
