laplacetransform-cos(2t)

Lösung

laplace transformation

- cos (2 t)

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

Schritte zur Lösung

L {- cos (2 t)}

Verwende die konstante Multiplikationseigenschaft der Laplace-Transformation:

For function

f (t)

and constant

a : L {a \cdot f (t)} = a \cdot L {f (t)}

= - L {cos (2 t)}

L {cos (2 t)} : \frac{s}{s ^{2} + 4}

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

\int 21 x sec^{2} (x) d x

\int \frac{1}{x ln ( x ) ln ( ln ( x ) )} d x

d er i v a t i v e f (x) = 1 1^{x}

\frac{\partial}{\partial x} (\frac{x + y + z}{3})

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