Question

Show that the laplace transform of \(f(ct)\) is \[\frac{1}{c}F(\frac{s}{c})\]

Answer 1

@modphysnoob help?

Answer 2

anyone please?

Answer 3

well, do you want worked example or why that is true?

Answer 4

i want to know how to prove it

Answer 5

well, remember this

derivative in time domain is multiplication by s in laplace domain

Answer 6

ok i think i can do it myself... i substitute ct with u, so -st becomes \(-u\frac{s}{c}\) and then i take the integral of it
