expand cos(t)h(t-7)

expand

cos (t) h (t - 7)

t h cos (t) - 7 h cos (t)

Solution steps

cos (t) h (t - 7)

= h cos (t) (t - 7)

Apply the distributive law:

a (b - c) = ab - a c

h cos (t) (t - 7) = h cos (t) t - h cos (t) \cdot 7

= h cos (t) t - h cos (t) \cdot 7

= t h cos (t) - 7 h cos (t)

\frac{( 500 + 500 x )}{( 1 + 0.01 x ^{2} ) ^{2}}

(e^{2 t} - \frac{1}{2} e^{- t})^{2}

(10 x - 1) (\frac{1000 x ^{3} - 10 x + 2}{10 x - 1} + 1)

\frac{1}{s ^{2} ( s ^{3} + s ^{2} )}

(\frac{x}{9} + 1)^{2}
