Using this **online graph plotting software** is easy. It acts like an online virtual TI-84 graphing calculator All you have to do is click the keyboard icon in the bottom left corner of the online curve plotter to show the keypad.

Then enter your expressions for X in the equation box using the keyboard.

It’s that easy. Now just watch your graphed line or curve appear. 🙂

### How to Plot Multiple Functions Online

You can plot multiple functions, lines, or curves on the same graph pretty easily. Simply, click below your current equation and another formula text box will appear for your next equation.

You can either use the on screen keypad or your computer keyboard to enter in another expression or formula.

Then just hit enter.

### How to Remove Functions from the Graph

To remove any curve or line plotted on the graph, simply click the X in the top right corner of the equation or function box. This will remove the function from the graph.

### How to Rearrange Function Order on the Graph

If you want to move the second function to the first function position on this graphing calculator TI-83 online, simply click and drag the second function above the first. It will now take the place of the first.

### How to Zoom on a Point, Intersect, or Curve

All you have to do to zoom in on any piece of data on the graph is to click the plus and minus symbols on the top right corner of the graph. You can also use your mouse scroll wheel if you are using a computer.

If you want to zoom back out to the original view of the graph, simply click the home icon on the right side of the graph. This will return you to the standard graphing view.

### How to Switch Between Radians and Degrees

Switching between Radians and Degrees views is simple. Click the wrench icon in the top right corner of the graph and a settings tab will appear. At the bottom of the settings tab, click Radians or Degrees.

### Switch Between Linear and Radial Grids

You can switch your graph from a linear grid format to a radial format by clicking the wrench icon in the top right corner of the graph and then clicking one of the two circle icons below the word Grid.

## Online TI-84 Graphing Calculator Functions and Capabilities

This **online graphing calculator TI 84**version has all of the same functions that a standard TI-84 does.

### Graphing Functions

This calculator can plot the following functions:

- Linear functions
- Quadratic functions
- Cubic functions
- Quartic functions
- Trigonometric functions
- Polynomial functions
- Hyperbolic functions
- Logarithmic functions
- Exponential functions
- Piecewise functions
- Inverse functions

### Advanced Capabilities

This online calculator is also capable of graphing arbitrary inequalities, conic sections, and slope fields.

#### Adding Tables

You can add tables to your graph by clicking the Plus icon in the top left corner of the functions box and then clicking add table. This will insert a text field for you to enter your table data into the graph.

#### Adding Notes

You can also add notes to your graph the same way you added the table. Simply click the Plus icon and click add notes. This will create a text field in the functions box to enter whatever note you want to add to your graph.

## Common Graphing Questions

### Is there a graphing calculator app?

Yes, GraphCalc is one of the first Windows graphing calculator software packages that allows you graph all functions and equations in a single app either online or on your computer, tablet, or phone.

### Can you graph a scientific calculator?

In short, no a standard scientific calculator can’t graph. A scientific calculator is not meant to graph equations and generally lacks the screen necessary to display a graph. Typically, scientific calculators only perform calculations like addition, subtraction, multiplication, and division. They are also capable of more advanced functions like trigonometric functions, logarithms, and exponents.

### Can you graph Trig functions on a calculator?

Yes, you can easily graph trig functions on a graphing calculator. Here are the steps to graphing a trig function:

- Press Mode and select Radian and Function
- Use the Y=editor to enter your Trig functions
- Press Zoom to graph your function

### How much is a graphing calculator?

Standard graphing calculators like the TI-83, TI-83 Plus, or TI-84 typically cost $100-$150. You can find them cheaper than that if you buy one used, but that is the standard list price.

The GraphCalc graphing calculator is FREE. It performs all of the same functions as the Texas Instrument calculators, but you don’t have to waste a ton of money on it.

### What is the best graphing calculator for high school?

The best graphing calculator for high school students depends on the student and their classes. For example, some students need something portable and easy to grab or put in a small bag. A traditional calculator might work well for them. Other students who want more functions and the ability to use bigger screens will probably like the GraphCalc calculator better. It really depends on the student.

### How do I graph a list on a TI-84?

Graphing a list is simple. Here are the steps to graph a list:

- Press 2nd STAT PLOT
- Clear any functions in Y1
- Press STAT EDIT and enter data in the L1 and L2 lists
- Press 9: ZoomStat to see your scatter plot
- Press TRACE to use the arrow keys to view each data point

### Are graphing calculators allowed on the SAT?

Typically, the testing center will not provide a calculator for you or allow any calculators for non-math exams. They will, however allow you to bring your own graphing calculator to both Mathematics Level 1 and Level 2 exams.
