laplacetransform cos(ax+b)

laplace transform

cos (a x + b)

\frac{s cos ( b ) - a sin ( b )}{s ^{2} + a ^{2}}

Solution steps

L {cos (a x + b)}

Use Laplace Transform table:

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

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

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