Question

laplace transformations

Answer 1

hmmm what do u mean squiggly U?

Answer 2

my book write the heaviside function as a squiggly U
\[\mathcal{L}\{\cos 2t \mathcal{H}(t-\pi)\}\]

Answer 3

U for unit step function

Answer 4

same thinggggg
\mathcal{U}

Answer 5

except it didnt look squiggly enough

Answer 6

use t axis shifting property

Answer 7

oh wait does this mean i dont have to do all this nonsense integrating

Answer 8

may I ask if we are allowed to use laplace transforms tables

Answer 9

if you're refering to cos and sin, i have those so yes

half way through integrating a piecewise function...

Answer 10

you are on right path if you start integration

Answer 11

its not very fun

Answer 12

\[=\frac{s e^{-\pi s}}{s^2+4}\]

integration by parts is not very fun either

Answer 13

cant disagree

Answer 14

if only i had read the translation theorem before bothering to attempt this
