function grapher

<p>Anyone know of a decent function grapher that is free and I can download or use online? I'm doing a calc project and having trouble finding one that will put in the circles that indicate whether a point is included or excluded.</p>

<p>Thanks</p>

<p>Wow, I didn't know they had emulators for graphing calculators.</p>

<p>Simply tell your calculus teacher that math classes shouldn't have projects. Our calc teacher would never give us a project. We debated that with the stats teacher and she just flipped and sent kids to the office...but math=no projects...</p>

5

<p>I don't know about the other models but TI 83+(the only rom I would have access to) doesn't have the circle things so VTI won't really work</p>

<p>I doubt a lot of calculators would do the circle thing though.. maybe you can just draw them yourself, if that is what your project requires?</p>

<p>Oh I probably wasn't clear, my original post was about programs for the computer, not for calculators.</p>

<p>TI 83+ can do the circle thing, but it will not show excluded points. The only calculator that I have found that does it is the TI-89, but I don't know that well how it works.</p>

whether the point is inside a circle or not? Is that what you are asking?</p>

<p>He is asking about the edge of a circle and its domain definition.</p>

12

<p>arg i'm going to draw a picture on paint and link it to be more clear</p>

13

<p>consider this a piecewise function(yes i know it doesn't pass vert. line test)</p>

<p>I just mean the circles that indicate whether a point is included or excluded</p>

14

<p>Ah, you meant whether or not the function was defined at some place in the domain and whether or not it had discontinuities; I think you can use dot mode and it might still work. By any chance are you doing something on continuity or differentiability now?</p>

15

<p>the project is to make a review notebook on everything we have covered in calc bc</p>

<p>Then most of that stuff can be drawn, and you can make up easy functions that don't require too much use of a GC or GC emulator.</p>
