SinReg [iterations,
Xlistname,Ylistname,
period,regequ]
Attempts iterations times
to fit a sinusoidal
regression model to
Xlistname and Ylistname
using a period guess, and
stores the regression
equation to regequ.

solve(
expression,variable,
guess,{lower,upper})
Solves expression for

guess and lower and upper
bounds within which the
solution is sought.
