    Laplace Transform of cos(kt) using Power Series expansion

    oh..ok i see, i was forgetting to input the bounds, this causes each term to go to zero except for the last one, where the exponent of t is 0. Thanks.

    Laplace Transform of cos(kt) using Power Series expansion

    Homework Statement The problem just states to find the Laplace Transform of cos(kt) from its power series expansion, instead of using the formula for the transform of a periodic function.Homework Equations Equation for Laplace transform of a function f(t) ->\int(e^{-st}f(t))dt Power Series...

    Magnetic dipole moment homework

    (sorry for all the greek letters in superscript, I don't know why it's doing that...) I am doing this same question except the sphere only carries a uniform surface charge \sigma. I then obtain the final answer 4/3\piR\omega\sigma Which is equivalent to Volume of Sphere x...

    Write the Magnetic Field of a dipole in coordinate-free form?

    Homework Statement Show that the magnetic field of a dipole can be written in coordinate-free form: B_dip (r)=(μ_o/(4πr^3 ))[3(m*r ̂ ) r ̂-m] Homework Equations Adip(r)= (μ_o/(4πr^2))(m*sin(theta))...
