simplify sin(a)-sin(a)cos^2(a)

simplify

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

sin^{3} (a)

Solution steps

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

Use the Pythagorean identity:

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

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

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

Factor out common term

sin (a)

= sin (a) (- cos^{2} (a) + 1)

= sin^{3} (a)

(x - 1)^{3} - (x + 2) (x - 3)

x^{2} e^{\frac{- y ^{2}}{x ^{2}}}

5 \frac{m}{s}

(2 x + p - c)^{2} - (2 x - p + c)^{2}

aa + 30 - 10
