Hello

I have an expression, say 

v(t) = .5*(sum(abs(q)*(J*exp(q*j*Wc*t)+K1*exp(q*j*phiK1)*exp(q*j*(Wc+Wx)*t)+K2*exp(q*j*phiK2)*exp(q*j*(Wc-Wx)*t)), q = -1 .. 1))

When I raise this quantity to a power, say (v(t))^3, I want the answer as well in the form of a summation. This system is frequently encountered for a voltage source, and I am looking to segregate the harmonics generation through the use of the...
