Question

find Laplace transform of t cube cosat
​

Answer 1

Answer:

Table of Laplace bTransforms

f(t) F(s)

t sin a t 2 a s / (s 2 + a 2) 2

e -at sin b t b / ( (s + a) 2 + b 2 )

cos a t bs / (s 2 + a 2)

t cos a t (s 2 - a 2) / (s 2 + a 2) 2

Step-by-step explanation:

plz mark as brainlist and thanked me

Answer 2

Table of Laplace bTransforms

F(t) F(s).

t sin at 2as/(s2+a2) 2

e- at sin b tb tb/( (s+a)2+b2)

cos a t. bs/(s2+a2)

t cos a t. (s2-a2)/(s 2+ a 2 )2
