You must have dropped the calc at some point huh? Sounds like the LCD is broken. You can try resetting the MEM, but I doubt it'll work since these calcs don't have color displays and yours is showing a blue line. This leads me to believe that the LCD is broken. Live with it, have it repaired professionaly, or buy a new calc.

Syntax error for graphs


That hardly seems possible. Try graphing the function y=x.
There are a few ways to draw curves on this calculator
  1. Drawing functions
  • Type is y=f(X), the [X,theta, T] key enters X when pressed

  • Type POLAR r=f(theta), key [X,theta, T] enters theta w. pressed.

  • Type PARAMETRIC, requires an X=f(T) and Y=g(T) functions
9d190f54-442f-4986-bbd3-b968907454a5.jpg
  • Inequality graphing. You can also draw some functional inequalities such as y> 2X^2-3
  • Dynamic graphing (graphs where some parameter may be changing)
Drawing Relations
There are some other relation you can draw X=, X>, X< , and the drawing of general conics.

I hope that the foregoing remarks help you sort out the problem you are having. If they fail to do that, I suggest that you read the manual that shipped with your Prizm.

I am using a casio graphing calculator and I am trying to graph a parametric function. I put the mode on Param and I inserted xt and yt and i press draw. It draw but then stops and gives me an arugment...


The argument error must have something to do with the parametric functions you are drawing. I do not think anybody would know where to look unless you give us the functions.
As to the range of the T-variable, you can set it by pressing [SHIFT][F3] to open the (V-Window) configuration screen. It starts showing Xmin, Xmax. etc. To get to the T range, use down arrow (about 7 times).

How to use graphing calculator?


The casio FX-300Ms calculator cannot do graphs. To tell you how to use a graphing calculator TO DRAW GRAPHS we need to know the exact brand and model number of the calculator.

  1. Most graphing calculators basically function the same way.
  2. You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
  3. You enter the algebraic form of the function you want to draw.
  4. You press a button or menu to GRAPH
  5. The graph is drawn.
  6. If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
  7. Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
  8. You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.
In addition to its graphing capabilities, a graphing calculator can be used as a scientific calculator. Sometimes it can also do statistical and financial calculations, matrices, list manipulations, operations on complex numbers, text editing,, creating programs etc.

Your calculator is currently configured to draw polar graphs. To recover the more common Y= graphs,
  1. Press [MODE]
  2. Use down arrow 3 times to get to the line FUNC PAR POL SEQ
  3. Use left arrow to highlight FUNC and press [ENTER]
  4. Press [2nd][QUIT] to exit the MODE screen.
  5. Restart your graphing.

Graphic calculator texas:when i graph any function, it always says "invalid dim"


Hello,

A previous problem on statistics has turned the statistical graphs ON and that interferes with the graphing of functions.
TurnOff the STATPLOTS by pressing [2nd][STAT PLOT][4:PlotsOFF]. Command echoes on the home screen. Press ENTER. I was going to add to reset all ram just in case.
Make sure you are drawing the right type of graph. To check that press [MODE], scroll down to 4th line to highlight Func and press ENTER, if you are drawing y=f(x) functions. The others are PARametric, POLar, SEQuence.
Hope it helps.

I dont know how to graph


Hello,
Turn calculator [ON]. If you do not see the menu icons, press [MENU]. Use the arrow keys to highlight the [GRAPH] icon.
An entry screen appears where you enter the functions you want to graph.
On the first line you have Y1= . After the equal sign enter 2[x] [X, theta,T] + 1. When finished press [F6: Draw] Your graph appears on the screen. If you see the axes, but no graph, press [Shift][V-Window] and press [F3:Std] then [SHIFT][QUIT] will take you back to the screen where you enter the functions to draw. There press [F6:Draw].

Hope it helps.

Hello,
You were lucky not to see the dimension problem with the TI83Plus.
