Could you guys do me a favor for solving a equation set? Z=d/4*(1-SIN(X)/X) X=8q/(D^2*Y)+SIN(X) Y=1/n*Z^(2/3)*i^(1/2) In this equation set, X,Y&Z are the unkown parameters, the others say, d, q, n&i are known. SO in python, how to program it to represent X, Y and Z in the form of d, q, n and i? Thanks very much.
