laplacetransform cos(t)

laplace transform

cos (t)

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

Solution steps

L {cos (t)}

Use Laplace Transform table:

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

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

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

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

x \to 0 lim (1 - sin^{2} (x))

\int (cos (2 x))^{2} d x

\int \frac{( x - 2 )}{x} d x

x \to \infty lim (x \cdot (- 1))

\int (5 - x)^{2} d x
