Unfortunately, that means that it won’t handle discontinuities in the way one might like. (For example, a jump discontinuity would be drawn connected with a line, rather than disconnected.) Similarly, infinitely small holes won’t appear. You can, however, draw the hole on later manually in a graphics editor, if that helps in some way. I’ll consider adding the ability to add such points later, but at the moment, it’s effectively not possible.

Sorry, hopefully that explains things a bit. Thanks again.

a. lim f(x) = 0
x ® -1 –
b. lim f(x) = -1
x® -1 +
c. lim f(x) = 1
x® 0
d. f(0) = 0
e. lim f(x) = 2
x® (infinite)

You can multiply by other conditions to add further conditions, generally using > or < will work. From there, add more terms to the sum in order to add more pieces to your piecewise function. (This has two side-effects: Where the piecewise function is undefined, the value will be zero, and vertical lines will be formed where there is a discontinuity.)

Hopefully this helps.

If, on the other hand, someone comments that they would like the option to keep them labeled, I can add that as an option, although I think that at the moment, an extra feature to keep that labeled is unnecessary and would add clutter.

Thanks again! Hopefully this change helps make GraphSketch more usable.

(Fractional exponents don’t work well with the software I’m using to produce the graphs. If I find a way to make fractional exponents more standard in the future, I will try to do so.)

Thanks!

For example, “the base 2 log of x” can be written as (log(x)/log(2)). (The extra parentheses aren’t necessary in this simple example, but could be if you use the expression as an exponent.)

Hopefully that helps you for the time being. Thanks!
