how does the value of "a" affect Lemniscate curves?
Does it just affect how far the curve is stretched to both sides?

Also when you graph an archimedes spiral for r = theta
theta is greater than or equal to 0 theta >_ 0:

How would the windows on a graphing calc be set ...... would this be x min , xmax or y min, y max
Thanks!
