laplacetransform cos(x)

laplace transform

cos (x)

\frac{s}{s ^{2} + 1}

Solution steps

L {cos (x)}

Use Laplace Transform table:

L {cos (a t)} = \frac{s}{s ^{2} + a ^{2}}

L {cos (x)} = \frac{s}{s ^{2} + 1 ^{2}}

= \frac{s}{s ^{2} + 1 ^{2}}

= \frac{s}{s ^{2} + 1}

\frac{d}{d x} (x e^{- x})

(- 2, 1), (1, - 2)

\int cos (x) (5 + 8 sin^{2} (x)) d x

\int_{1}^{2} x^{\frac{1}{2}} d x

x, x^{2} - 1, 0, 1
