Inverse Laplace Transform

Find the inverse Laplace transform of the following in the attached file. Thanks.

Transfer Function

A battery of voltage Vi is connected in series with a resistor of resistance R, an inductor of inductance L and a capacitor of capacitance C. If, the output voltage across capacitor is Vo, derive the transfer function.

Second order to first order

Find the equivalent first-order system (that is, find the matrix A and the vector R of dv/dx = Av + R) for the second order equation (see attachment for equation)

Initial value problem

(See attached file for full problem description with proper symbols) --- 1. Solve the initial-value problem d2u/dt2 + w2u = (w2-2)cos(t), u(0)=2, du/dt (0) = 0 where w and  are constants. Show that the solution can be written in the form 2cos(t)cos(t) where =(-w)/2 a ...continues

Euler's equation

Euler's equation states (z^2)w'' + αzw' + βw = 0 where w'=dw/dz If we substitute in w=z^u into Euler's equation, we find the so-called indicial equation: u^2 + (α-1)u +β=0 Use the change of variable t=ln(z) in the Euler equation to show that the Euler equation has the linearly independent pair of solut ...continues

General Solution to the Differential Equation

Help! I am having a problem with this homogenous differential equation (y^2 + yx)dx + x(^2)dy=0 I tried substitution of x = vy, dx = vdy + ydv, but I am not quite getting it right. Please help!

Difficult Diff. EQ

This problem is really giving me issues, as I do not even know how to set it up to solve it. Please solve this problem in as much detail as possible. I guess the number 1 in the parentheses is what is confusing me. Thank you so much! (1 + x^2 + Y^2 +(x^2)(y^2))dy = (y^2)dx
