expand cos(2t)U(t-(13pi)/4)

expand

cos (2 t) U (t - \frac{13 π}{4})

t U cos (2 t) - \frac{13 π U cos ( 2 t )}{4}

Solution steps

cos (2 t) U (t - \frac{13 π}{4})

= U cos (2 t) (t - \frac{13 π}{4})

Apply the distributive law:

a (b - c) = ab - a c

a = cos (2 t) U, b = t, c = \frac{13 π}{4}

= cos (2 t) U t - cos (2 t) U \frac{13 π}{4}

= t U cos (2 t) - \frac{13 π}{4} U cos (2 t)

Simplify

t U cos (2 t) - \frac{13 π}{4} U cos (2 t) : t U cos (2 t) - \frac{13 π U cos ( 2 t )}{4}

= t U cos (2 t) - \frac{13 π U cos ( 2 t )}{4}

\frac{( 8 + x ^{2} ) ^{2}}{16}

2 (x - \frac{π}{4})

\frac{290400 x ( - x + 1 )}{145 x ^{2} + 2 x + 1}

\frac{1}{( s ^{2} + w ^{2} ) ( t s + 1 )}

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