1. Meiss, p. 26, problem 10a. To avoid Greek letters, you can make the change of variables as we did in lecture: call the new variables (u,v,w) and the new time s, and let x=mu, y=nv, z=pw, t=qs. Find m, n, p, q that put your differential equation into the simplified form given in the table. Be sure to give formulas for the remaining parameters in terms of the original parameters.
