expand-2usin(t)(t-pi)

expand

- 2 u sin (t) (t - π)

- 2 u t sin (t) + 2 π u sin (t)

Solution steps

- 2 u sin (t) (t - π)

Apply the distributive law:

a (b - c) = ab - a c

a = - 2 u sin (t), b = t, c = π

= - 2 u sin (t) t - (- 2 u sin (t)) π

Apply minus-plus rules

- (- a) = a

= - 2 u t sin (t) + 2 π u sin (t)

\frac{( x + 3 ) ( x - 2 )}{x - 3}

arctan (f (5 x^{5} - 1))

x (1 + x)^{2}

\frac{( s ^{2} + 6 s + 9 )}{( s - 1 ) ( s - 2 ) ( s + 4 )}
