Homework Statement Well i did all my work but the forum logged me out and when i submitted it I lost it all because it wanted me to login again >_< anyways i need to find the inverse laplace transform of F(s)=[12*s^2 - (28+2*sqrt(3))*s + 26 + 6*sqrt(3)]/[(s-3)(s^2-2s+2)] Homework...

Homework Statement Find thevenin equivelent of this circuit with respect to a and b Homework Equations Mesh Currents The Attempt at a Solution Here I will try to find V(open circuit) = Vth = Vab ((I think this anyways)) I apply mesh currents (any faster methods are welcome if...

Every single example i have seen of eulers method starts with a range of 0 to some number, what if you had it going from like 2 to some number? for example if we had x'=2x^2 + tx x(2)=1 and our range was 2 <= t <= 2.5 with h = .25 would I do this? x(2.25)=x(2)+f(x(2),0)*.25 =...

Homework Statement Consider the matrix [1,-5,5;-3,-1,3;1,-2,2] Do four interations of the power method, beginning at [1,1,1] to approximate the dominant eigenvalues of A Homework Equations Matrix multiplication The Attempt at a Solution Okay my issue with this problem is this I...

so would my answer just be q/(4*pi*epsilon(sub0)*r^2) ?

The center of the sphere will be located on the point charge

I feel that a sphere represents a good shape.

what do you mean by exploit?

A point charge inside infinite dielectric material 1. The problem statement, all variables and given known data A point charge is an infinite medium of dielectric material having a relative permittivity \epsilonr. <--- epsilon(sub r). Find the electric field vector and the potential function...

Thanks man I would never figure that out!

Homework Statement Suppose that L is a second order linear differential operator over the interval J, that f is a function defined on J, and that the function v has the property that Lv = f on J (a) Show that if y = u + v and that Lu = 0 on J, then Ly = f on J (b) Show that if Ly = f on...

I solved it with coefficients! XD I compared the right and left side to the coefficient s I got that 0 = C now if i set s = 1 I get 1 = 5/4 + B B = -1/4 Woot :)

Im sorry but I don't follow

I don't know. i = 1/C ?

Homework Statement 1/[s*(s^2 + 4)] Homework Equations The Attempt at a Solution 1/[s*(s^2 + 4)] = A/(s) + (Bs + C)/(s^2 + 4) => 1 = A(s^2 + 4) + (Bs + C)s s = 0 1 = A(0 + 4) + (B*0 + C)*0 A = 1/4 s = i 1 = A(i^2 + 4) + (Bi + C)i 1 = A(i^2 + 4) + Bi^2 + Ci 1 =...
