erweitern (1+5sin^2(t))(5sin(2t))

Lösung

erweitern

(1 + 5 sin^{2} (t)) (5 sin (2 t))

5 sin (2 t) + 25 sin^{2} (t) sin (2 t)

Schritte zur Lösung

(1 + 5 sin^{2} (t)) (5 sin (2 t))

= (5 sin (2 t)) (1 + 5 sin^{2} (t))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

(5 sin (2 t)) (1 + 5 sin^{2} (t)) = 5 sin (2 t) \cdot 1 + 5 sin (2 t) \cdot 5 sin^{2} (t)

= 5 sin (2 t) \cdot 1 + 5 sin (2 t) \cdot 5 sin^{2} (t)

Vereinfache

5 sin (2 t) \cdot 1 + 5 sin (2 t) \cdot 5 sin^{2} (t) : 5 sin (2 t) + 25 sin^{2} (t) sin (2 t)

= 5 sin (2 t) + 25 sin^{2} (t) sin (2 t)
