a differential equation question:
find l\left \{ t^2e^4^t \right \}

Step-by-step explanation:

To find Laplace transform of

We know that Laplace transform for

is

, for all n = 1,2,3.... and real values a..

Here n =2 and a=4

Hence substituting we get

Laplace transform of given term is

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

1010: 3030

is it i think
