Can someone explain how to graph polar coordinates on a TI-84 Plus calculator-I can't find the directions anywhere
Thank you
If someone could explain how to set up the TI-84 P;lus to graph polar coordinates (3,15degrees) then I'll use that as an example. I know it has to be in degrees and then the y= appears but what then??
Thank you
Sure! I can guide you through the steps to graph polar coordinates on a TI-84 Plus calculator. Please follow the steps below:
1. Turn on your TI-84 Plus calculator by pressing the "ON" button.
2. Press the "MODE" button located at the top left corner of the calculator. This will bring up the mode menu.
3. Use the arrow keys to navigate to the "POL" option, which stands for polar mode. Press the corresponding number key (usually 3) to select this mode.
4. Press the "Y=" button, which is located below the screen. This will bring up the function editor.
5. Enter the polar equation you want to graph using the variables "r" (radius) and "θ" (theta). For example, if you want to graph the circle with radius 3, you would enter "3". If you want to graph a cardioid, you would enter "1 + cos(θ)".
6. After entering your equation, press the "GRAPH" button (located to the right of the arrow keys) to plot your graph.
7. To adjust the window settings, press the "WINDOW" button located below the "Y=" button. From there, you can change the x and y ranges to fit your desired graph.
8. Press the "ZOOM" button below the "WINDOW" button to access the zoom menu. You can choose from different options such as "ZSquare" or "ZoomFit" to adjust the graph display.
9. Once you have finished adjusting your window and zoom settings, press the "GRAPH" button again to update the graph according to your preferences.
That's it! You have successfully graphed polar coordinates on your TI-84 Plus calculator.
Sure! I can help you with that.
To graph polar coordinates on a TI-84 Plus calculator, you can follow these steps:
1. Turn on your calculator and press the "MODE" button.
2. Use the arrow keys to scroll down to the "POL" option in the mode menu, which stands for polar coordinates. Press the "ENTER" button to select it.
3. Press the "Y=" button to enter the equation editor.
4. Enter the equation or polar coordinates you want to graph in the form of r = f(theta), where "r" represents the distance from the origin, and "theta" represents the angle in degrees.
5. After entering the equation, press the "GRAPH" button to plot the graph.
It's important to note that when graphing polar equations, you need to make sure that the viewing window settings are appropriate for the equation you're graphing. If the graph does not appear on the screen, you might need to adjust the window settings.
To adjust the window settings for polar graphing on the TI-84 Plus calculator, you can follow these steps:
1. Press the "WINDOW" button.
2. Adjust the values for "ThetaMin" and "ThetaMax" to set the range of angles for your graph. These values represent the minimum and maximum angles in degrees.
3. Adjust the values for "rMin" and "rMax" to set the range for the radial distance from the origin.
4. If necessary, adjust the values for "Xscl" and "Yscl" to change the scaling of the x- and y-axes.
Once you have set the appropriate window settings, you can press the "GRAPH" button again to see the updated graph.
I hope this helps! Let me know if you have any further questions.
