erweitern cos(t)μ(t-pi/2)

Lösung

erweitern

cos (t) μ (t - \frac{π}{2})

t μ cos (t) - \frac{π μ cos ( t )}{2}

Schritte zur Lösung

cos (t) μ (t - \frac{π}{2})

= μ cos (t) (t - \frac{π}{2})

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = cos (t) μ, b = t, c = \frac{π}{2}

= cos (t) μ t - cos (t) μ \frac{π}{2}

= t μ cos (t) - \frac{π}{2} μ cos (t)

Vereinfache

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

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