vereinfachen 1/81 (sin(9(t-x)))+9xcos((t-x)9)

Lösung

vereinfachen

\frac{1}{81} (sin (9 (t - x))) + 9 x cos ((t - x) 9)

\frac{1}{81} sin (9 (t - x)) + 9 x cos ((t - x) \cdot 9)

Schritte zur Lösung

\frac{1}{81} (sin (9 (t - x))) + 9 x cos ((t - x) \cdot 9)

Apply rule:

(a) = a

(sin (9 (t - x))) = sin (9 (t - x))

= \frac{1}{81} sin (9 (t - x)) + 9 x cos ((t - x) \cdot 9)
