simplify (2cos(t)-2sin(t))(-2sin(t))

simplify

(2 cos (t) - 2 sin (t)) (- 2 sin (t))

- 2 sin (t) (2 cos (t) - 2 sin (t))

Solution steps

(2 cos (t) - 2 sin (t)) (- 2 sin (t))

Apply rule:

a (- b) = - ab

(2 cos (t) - 2 sin (t)) (- 2 sin (t)) = - (2 cos (t) - 2 sin (t)) \cdot 2 sin (t)

= - (2 cos (t) - 2 sin (t)) \cdot 2 sin (t)

= - 2 sin (t) (2 cos (t) - 2 sin (t))

(z - \frac{1}{2}) (z + \frac{1}{4})

(\frac{x + y}{x} - 1) (\frac{x}{y} + 1)

100 cos (\frac{π}{600}) (x - 400) + 50

2 x (3 + x^{3})
