Homework Statement Find the complex Fourier series of the periodic function f(t)=2sin(πt) 0 < t < 1 and f(t+1) = f(t) for all t. (π is pi)Homework Equations http://upload.wikimedia.org/math/9/d/7/9d7f73fbcba87cbff485e66646aa541d.png...

okay thanks for clearing that up, but what about the general solution for Θ(θ)? still not sure on that...

Homework Statement Look for a seperable solution T(r,θ) = R(r)Θ(θ) and derive equations for R(r) and Θ(θ) choosing a separation constant that gives sinusoidal solutions for Θ(θ). Write down a general solution for Θ(θ) and show the equation for R(r) has solutions of the form R(r)=r^p. Homework...

Homework Statement Consider a plane-polarised electromagnetic wave in source-free vacuum, with magnetic field B = (1,1,0)BoCos(kz-wt), with Bo = 0.001 Tesla. Find (1) the direction of propagation of the wave, (2) average energy density carried by the wave, and (3) the fraction of this...
