Function Grapher and CalculatorThe Function Grapher and Calculator is ready for you guys to try out. There are probably still bugs, and I don't mind if you tell me about them.

Re: Function Grapher and CalculatorBrilliant! Character is who you are when no one is looking. #4 20060604 08:23:15
Re: Function Grapher and CalculatorI think the little box which pops out when you click calculate is cool. #5 20060604 10:26:52
Re: Function Grapher and CalculatorIt seems that the values are so far out of bounds they oscillate between plus and minus, and so make lots of vertical lines. I will get it to show me the values, and sift through to see why. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #6 20060604 17:03:49
Re: Function Grapher and CalculatorI think I have ironed that particular bug out: Torture Test "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #7 20060607 15:12:14

Re: Function Grapher and CalculatorCtrlc sometimes works with flash, but the most reliable is rightclickselect all, then rightclickcopy "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #9 20060609 21:02:36
Re: Function Grapher and CalculatorI don't understand...I don't understand...I don't understand...I don't understand...BLAM... Chaos is found in greatest abundance wherever order is being saught. It always defeats order, because it is better organized. #10 20060724 06:14:51
Re: Function Grapher and CalculatorThis is fun to play around with when you're bored. Nice work. #11 20060731 19:34:56
Re: Function Grapher and CalculatorAn upgrade to the function grapher. It now understands "2x" as being "2 times x". Likewise it understands 2pi, 2(x+1) and even (x+1)(x+1).

Re: Function Grapher and CalculatorBump. Why did the vector cross the road? It wanted to be normal. #13 20071218 07:18:36
Re: Function Grapher and CalculatorI will look into it! "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #14 20080731 11:40:13
Re: Function Grapher and CalculatorI've been spending about 2 hours solid fiddling with this function grapher. igloo myrtilles fourmis #15 20080731 12:00:13
Re: Function Grapher and CalculatorThanks John. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #16 20080731 13:06:17
Re: Function Grapher and CalculatorYou can also find the missing lines with y=x^2, igloo myrtilles fourmis #17 20090302 09:00:57
Re: Function Grapher and CalculatorI have an updated version (0.96) now ... Function Grapher and Calculator "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #18 20090302 10:03:03
Re: Function Grapher and CalculatorNice upgrades! Why did the vector cross the road? It wanted to be normal. #19 20090302 10:44:01
Re: Function Grapher and Calculator
Yeah ... it needs time to draw the graph. I thought of partdrawing the graph, or drawing it in lowres (every 4th pixel) while you are dragging  I am not sure it would be better though ?
Oops ... fixed.
Good idea "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #20 20100127 04:40:35
Re: Function Grapher and CalculatorMIF, here are 2 function graphers. igloo myrtilles fourmis #21 20100127 07:19:01
Re: Function Grapher and CalculatorSame? Would the other one be "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #22 20100127 08:57:07
Re: Function Grapher and CalculatorSorry, my forgotten cut and paste. Should be: igloo myrtilles fourmis #23 20100608 03:46:51
Re: Function Grapher and Calculator
I think you have a winner. Graphs are a big help in the understanding of math. #24 20100608 07:45:41
Re: Function Grapher and Calculator
Yes, well said, especially in determining the number of zeroes that a polynomial has and where they are. Other types of functions even more so! With the new graphing calculators and CAS they are fun to do also. When I started they only gave us a beach full of sand to draw on and some pebbles to count with. Some of us were eaten by sharks, math was more dangerous then. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #25 20100615 20:50:34
Re: Function Grapher and CalculatorVery nice, is it done in Flash? Can feel it coming together.. Slowly but Surely
