Question about Texas Instruments TI-86 Calculator

2 Answers

Graphing x=f(y) I'd like to graph functions of the form x = f(y).Is it possible to graph the function: x=4 or x = sin(y)?It seems that you can only graph functions of the form y=f(x).

Sorry to tell you this, but you can't graph any of those. Good luck

How do I graph x<-3 on the calculator?

First you must use a graphing calculator.
Most graphing calculators graph functions, i.e. relations of the form y=f(x).
Some graphing calculators are able to graph equations (not necessarily functions). On one of these calculators your draw the vertical line x=-3, then you shade to the left of the point x=-3. That gives you the real line from infinity up to but not including x=-3.
Generally, people do not need calculators to find the solutions to inequalities in just one variable.

Finding a limit "a" on an integral with a fixed area

There are several ways of doing this.

Since you're using a graphing calculator, you can always graph it as a function of 'a' and use the graphical tools.

Another way is to use the solve() function. For example, to find the value of a where the integral of sin(x) from 0 to a equals one, enter

solve( and fnInt( are accessible through the CATALOG. The 1.5 is an initial guess.

When I type in a function for y1 and have it in standard form the calculator says range Error. How do I change the range, because it wont let me go to the graph. Which is where I would then click V-window...

A linear function in standard form is of the form Ax+By+C=0, where A is a positive integer, B and C are integers (positive or negative).
The problem is that calculators graph a function given in functional form y= ax+b.Thus to graph a function in standard form by means of a graphing utility you must isolate the y variable. The interesting thing about the Prizm (Casio graphing calculator) is that you select which variable to isolate y (usually) or x if you so choose. To choose to graph the function x=Dy+E you must select the function type as X=.

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
  • 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.

When i try find graph for sin or cos x or even yan i get a always tright line

Set your calculator to RAD mode and then graphing functions.
See example for y=sin x

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.

Graphing function barely works (can enter a number on the y= and it will draw a line), but most buttons cause the >sin entry. Can do basic addition, subtraction, etc. Tried to reset by taking out all...


if you put y= 3 or something like that; than your going to get a line try y1= 2x+3 for y1 and y2= -2x-3 press graph select zoomstd you should see two line form a x and some point if it does that that you calculator is okay . If all else check your manual and find the reset button this cure 99.99% all problems
