laplacetransform 7cos(3t)

laplace transform

7 cos (3 t)

\frac{7 s}{s ^{2} + 9}

Solution steps

L {7 cos (3 t)}

Use the constant multiplication property of Laplace Transform:

For function

f (t)

and constant

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

= 7 L {cos (3 t)}

L {cos (3 t)} : \frac{s}{s ^{2} + 9}

= 7 \cdot \frac{s}{s ^{2} + 9}

Refine

7 \frac{s}{s ^{2} + 9} : \frac{7 s}{s ^{2} + 9}

= \frac{7 s}{s ^{2} + 9}

\int (2 + x^{5})^{8} x^{4} d x

\frac{d}{d s} (\frac{s}{s ^{2} + w ^{2}})

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

\frac{d}{d x} (- 18 cos (3 x))

\int \frac{sin ^{5} ( θ )}{cos ( θ )} d θ
