expand rw(1-cos(wt),sin(wt))

expand

r \cdot w \cdot (1 - cos (w \cdot t), sin (w \cdot t))

1 \cdot w r - w r cos (wt), sin (wt)

Solution steps

r w (1 - cos (wt), sin (wt))

= w r (1 -, cos (wt) sin (wt))

Apply the distributive law:

a (b - c) = ab - a c

a = r w, b = 1, c = cos (wt), sin (wt)

= r w \cdot 1 - r w cos (wt), sin (wt)

= 1 \cdot w r - w r cos (wt), sin (wt)

\frac{( y + 1 ) ^{2}}{x}

tr (- x (x + 2) (x + 3))

x^{2} (\frac{x ^{2}}{2} - 2 y x)

(x - \frac{3}{5}) (x + \frac{3}{4})

\frac{1}{2} (x - 11) (6 + 2 x - 16)
