simplify sin(x)(-sin(x))

Solution

simplify

sin (x) (- sin (x))

Solution

- sin^{2} (x)

Solution steps

sin (x) (- sin (x))

Apply rule:

a (- b) = - ab

sin (x) (- sin (x)) = - sin (x) sin (x)

= - sin (x) sin (x)

Apply exponent rule:

aa = a^{2}

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

= - sin^{2} (x)
