Simple Laplace transform of a product of two trig identities of which I cannot remember how to integrate. See the attached file.

Use Laplace transform to solve an IVP style problem. Where y^n(t)+a^2y(t)=0 and a is not equal to zero.

Please see the attached file for the fully formatted problem. Suppose there was an IVP such as the following: where Where and how do you begin to set this problem up to be solved using the Laplace transform? The value y(4)(t) is the fourth derivative of function y(t).

I have a transform F(s) of which I need the inverse transform for. The form of the transform is not of a common form and I am having trouble reducing it to a workable form. I am looking at a problem that requires the inverse laplace transform of f(t) to be found using the following transform: F(s) = (s*e^(-s/2))/(s^2 + p

Solve the Laplace equation inside the quarter-circle if radius {see attachment} is subject to boundary condition: {see attachment} Thank you.

My problem deals with the Laplace expansion property applied to a exponential product function. I am unsure as to how the problem should be solved based on the given property formula and the Differential Equation books that I have used have been of no help. If familiar, please try to use the DiPrima notation.

The following is a sample test question involving the use convolution to find the inverse Laplace transform of the below equation. I have thus so far not been able to break the initial equation down into the two separate equations F(s) and G(s). Any help would be appreciated as it has been a while since I have used partial fract

You have been hired as a special consultant by u.s coast guards to evaluate some proposed new design for navigational aids buoys. The buoys are floating cans that need to be visible from some distance away without rising too far out of the water. Each buoy has a circular cross-section (viewed from below) and will be lifted with

A dynamical system, with one degree of freedom has Hamiltonian (see attachment for equation) ? Write down the Hamilton's equations governing the motion of this system, and deduce that H remains constant during the motion. ?

I've included the equation in the attachment. I realize that it is something larger than w, but I don't know how to get the antiderivative of f(x)f(1/x). Whoever helps me on this, please include more than just the answer in your reply. Thank you very much.

A water bucket is shaped like the frustum of a cone with height 24 inches, base radius of 6 inches and top radius of 12 inches. Water is leaking from the bucket at 10 cubic inches per minute. At what rate is the water level falling when the depth of the water in the bucket is 12 inches?

Use residue theory to compute the integral: Use residue theory to compute the integral: I know that the singular points are 4i and -4i, and that I need to integrate from -R to R and then around the half circle from 0 to pi. Only 4i is in this half-circle, so I need to calculate the residue for 4i. This is where I get stu
