erweitern cos(2t)U(t-(5pi)/2)

Lösung

erweitern

cos (2 t) U (t - \frac{5 π}{2})

t U cos (2 t) - \frac{5 π U cos ( 2 t )}{2}

Schritte zur Lösung

cos (2 t) U (t - \frac{5 π}{2})

= U cos (2 t) (t - \frac{5 π}{2})

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = cos (2 t) U, b = t, c = \frac{5 π}{2}

= cos (2 t) U t - cos (2 t) U \frac{5 π}{2}

= t U cos (2 t) - \frac{5 π}{2} U cos (2 t)

Vereinfache

t U cos (2 t) - \frac{5 π}{2} U cos (2 t) : t U cos (2 t) - \frac{5 π U cos ( 2 t )}{2}

= t U cos (2 t) - \frac{5 π U cos ( 2 t )}{2}
