laplacetransform cos(sqrt(2)t)

laplace transform

cos (2 t)

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

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} + 2}

y = 16 - x^{2}

\frac{\partial}{\partial x} ((a - x)^{2} + b (y - x^{2})^{2})

\int 6 x^{2} y d y

\frac{\partial}{\partial L} (b L^{3} K (b) (b)^{2})
