laplacetransform cos(2*t)

laplace transform

cos (2 \cdot 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{d y}{d x} = (x - 3) e^{- 2 y}, y (3) = ln (3)

y = lo g_{2} (lo g_{2} (x))

x \to 1 lim (- \frac{x ^{2}}{2} + 2 x + 4)

\frac{d}{d x} (\frac{x ^{3}}{3} - 10 x^{2} + 100 x)

(1 - x y) d x + (x y - x^{2}) d y = 0
