Graphing Definition and 498 Threads

A graphing calculator (also graphics calculator or graphic display calculator) is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are also programmable and therefore considered to be programmable calculators, allowing the user to create customized programs, typically for scientific, engineering and education applications. Because they have large displays in comparison to standard four-operation handheld calculators, graphing calculators also typically display several lines of text and calculations at the same time.

    Mathematica 3D Graphing (3D Plot) Issue

    I'm trying to graph two equations to compare the two visually. For some reason, one of them isn't showing up, even though I'm in a range to where it should be. See the screenshot below. The "3x - y = 4" is graphing fine, but for some reason, "x + y + z = 5" isn't showing up. At first, I...

    Range of a function involving trigonometric functions

    I resolved the numerator to ## cosx-sinx## We get $$mod\frac{cosx-sinx} {3(cosx+sinx)} $$ If we divide the numerator and denominator by cosx we get $$mod\frac{1-tanx} {3(1+tanx)}$$(eq1) We know that tan(π/4-x) is same as ##\frac{1-tanx} {1+tanx}## So re writing eq1 we get $$mod\frac{tan(π/4-x}...

    Graphing Elastic Potential Energy

    Good afternoon, I have a question on graphing this problem. There seems to be something weird going on. In Excel, I set up the potential energy function (kx²/2) and plotted it from x = -0.300m to 0.300m, which looks like the following: The overall shape of the graph looks like what's...

    Graph Sin(2x+6): Is Parent Function the Best Option?

    My question is when I start to graph sin (2x+6) I convert the expression to sin 2(x+3). My thinking that by doing so I can easily see the period is 2pi/2 and there is a horizontal translation of 3. Some books state that starting with sin(2x+6) the period is 2pi/2 , the same as above, and that...
