Lösung

n = 1 \sum \infty (sin (3))^{n}

Lösung

\frac{1}{1 - sin ( 3 )} - 1

+1

Dezimale

0.16430 \dots

Schritte zur Lösung

n = 1 \sum \infty (sin (3))^{n}

n = k \sum \infty (a_{n}) = n = 0 \sum \infty (a_{n}) - a_{0} - a_{1} - \dots a_{k - 1}

= n = 0 \sum \infty (sin (3))^{n} - (sin (3))^{0}

n = 0 \sum \infty (sin (3))^{n} = \frac{1}{1 - sin ( 3 )}

= \frac{1}{1 - sin ( 3 )} - (sin (3))^{0}

Vereinfache

= \frac{1}{1 - sin ( 3 )} - 1
