Nice graphing, but needs upgrades

Sat, 10 Mar 2012 17:20:08 -0500

I like this site, but I really need to find a graphing utility that will allow me to specify that the graph be proportional as well as show tick marks and grids. If the graphing utility could be upgraded to allow more user control over appearance of the graph it would be much more useful.

GR8 software. How do I retain the color of a graph when copying the image to the clipboard? Some of them dim or grey out.

Option for showing traces parallel to xy, xz, or yz planes separately?

Mon, 07 Mar 2011 18:40:19 -0500

Is there a way when doing the wire frame of 3-D surfaces to [u]only[/u] show particular traces? For example, consider the surface (x^2) +(y^2)-(z^2)=1. I want to be able to demonstrate to my students that the traces on planes parallel to the xy plane are circles. You can sort of make this point from the wire frame option but the traces on planes parallel to the xz and yz planes ...

the gender symbol

Wed, 16 Feb 2011 01:04:36 -0500

a problem i have noticed is that i selected male in my information but it sets me as a female with that symbol and i was wondering either if you could fix this problem or if you could allow members to be a be to switch once to allow correction of gender if a technical error such as mine occurs?

enlarging the keypad

Thu, 28 Oct 2010 15:36:14 -0400

I'm trying to help a student who is physically and visually impaired use this calculator. (I've purchased a monthly membership). I can enlarge the keypad onscreen (using Ctrl +) and center it for him to see, but then when a number is entered the keypad jumps back down on the screen. Is there a way to get rid of the ads at the top of the page or in some other way keep the keypad where I want it?

graphing inequality where the variable is an exponent

Sat, 28 Aug 2010 03:03:31 -0400

Hi. New to the site so maybe I missed this. Trying to graph y>=5^x-2 but the 2D inequality calculator doesn't seem to like this. Also, I don't see variables as exponents in any of the examples. Please help!

Graph Appearance Preferences

Wed, 04 Aug 2010 17:58:02 -0400

1. Is there any way to show gridlines on a graph? 2. Is there any way to just get a blank graph? 3. Once the max/min values are set for a graph, can the tick mark selection be adjusted. For example, instead of tick marks every 0.5, just by 1.

Please! Logging on

Fri, 12 Oct 2007 02:08:13 -0400

Can it be made that I don't have to logon every few minutes? If I'm doing homework, and turn my head for like 5 minutes, come back, fill the calculator in, and that darned oops message pops up.. it's darned annoying... can it be made that we stay logged in.. or at least until we close the window??? It's darned annoying.

need help

Sun, 10 Jan 2010 17:12:37 -0500

Hi all, I'm new to the site and congratulations to whoever did it. It's a v useful tool for Maths students and teachers. But now coming to the point, I've got a cruel doubt with a function sketch in my Maths assignment. Really appreciate if someone could give me a clue on how to get the graphic done. It's something like: f(x,y) = max {0,x^2+y^2-1} over the domain ||x||, ||y|| < or = 2. ...

6 month subscription ends after 8 days?

Tue, 03 Nov 2009 22:40:28 -0500

Hello, I just registered today, 11/3/09. In 'My Profile' my subscription shows it end in 8 days : "Your Current Subscription: 6-Month Subscription ends by 2009-11-11 17:31:53.0 " I'm sure this is just a database error, but I wanted to make sure there were no errors on my account. I would assume my subscription should end on 5/3/2010. Let me know and thank you.

Help using calculator

Sun, 25 Oct 2009 12:23:36 -0400

Hi, I just joined, and I am trying to imput a problem, but I apparently am not doing it correctly. The problem as it appears in my book is f(x)=2/3x^2-8/3x+5/3. I need to find the vertex, axis, domain and range, and then, graph it. I am supposed to be completing the square in order to find the vertex. I know that the calculator doesn't like the f(x). However, it seems like it wants me to ...
