expand cos(t)u(t-pi)

expand

cos (t) u (t - π)

t u cos (t) - π u cos (t)

Solution steps

cos (t) u (t - π)

= u cos (t) (t - π)

Apply the distributive law:

a (b - c) = ab - a c

a = cos (t) u, b = t, c = π

= cos (t) u t - cos (t) u π

= t u cos (t) - π u cos (t)

x^{2} \cdot (50 + \frac{3 x}{2}) - 1000 x

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

(y^{3}) d x + (3 y^{2} + 3 x y^{2} - y^{3}) d y

1 - s t e p (t - 1)

\frac{5 x ^{2} - 14 x + 13}{( x + 1 ) ( x - 3 ) ^{2}}
