expand cos(t-5)U(t-5)

expand

cos (t - 5) U (t - 5)

t U cos (t - 5) - 5 U cos (t - 5)

Solution steps

cos (t - 5) U (t - 5)

= U cos (t - 5) (t - 5)

Apply the distributive law:

a (b - c) = ab - a c

U cos (t - 5) (t - 5) = U cos (t - 5) t - U cos (t - 5) \cdot 5

= U cos (t - 5) t - U cos (t - 5) \cdot 5

= t U cos (t - 5) - 5 U cos (t - 5)

e^{4 x^{3} - 7 x^{2}} (24 x^{2} - 28 x)

\frac{4 x}{( x + 1 ) ^{3}}

(F (\frac{L}{3} - x) - \frac{w ( 5 x - 2 L ) ^{2}}{50}) (\frac{L}{3} - x)

(x - 3) (x + 1 + 2) (x + 1 - 2)

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