laplacetransform g(t)=cos(2t)

laplace transform

g (t) = cos (2 t)

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

Solution steps

L {cos (2 t)}

Use Laplace Transform table:

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

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

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

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

\frac{\partial}{\partial y} (tan (x^{2} - y^{2}))

x y^{^{'}} + y = 29 x

\int 4 - 4 x^{2} d x

2 x^{4}

\frac{d}{d x} (\frac{x ^{3}}{8})
