1) STOP SHOUTING!!!
Thanx...
For double inequalities, you need to specify each part separately. Also, by
putting all of it in one function, it is easier to trace. Don't divide,
multiply and add the products. Where an inequality is false, that term will
equal 0.
Note: this is not in the manual, I picked it up from years of programming
experience and a little ingenuity, and developed it when I needed to graph
piecewise functions easily (well, sort of)...
y1=(x^2)(x<0)+(x^3)(x>0)(x<1)+(2x-1)(x>1)
