laplacetransform cos(2t+pi)

Lösung

laplace transformation

cos (2 t + π)

Lösung

- \frac{s}{s ^{2} + 4}

Schritte zur Lösung

L {cos (2 t + π)}

Wende Laplace-Transformationstabelle an:

L {cos (a t + b)} = \frac{s \cdot cos ( b ) - a \cdot sin ( b )}{s ^{2} + a ^{2}}

L {cos (2 t + π)} = \frac{s cos ( π ) - 2 sin ( π )}{s ^{2} + 2 ^{2}}

= \frac{s cos ( π ) - 2 sin ( π )}{s ^{2} + 2 ^{2}}

= - \frac{s}{s ^{2} + 4}
