With the end of exams, it’s time to think about fun things we can do with math. Today’s post comes from a emailed question: “Can I produce a 3D plot on a TI-nspire?”
The answer is yes!
First, go to the home page. you want to select the button with the parabola on it (second from the left). It will say “Add graphs to new document.”
Now press the menu button and select View and then 3: 3D graphing.
You will now see a 3D cube and a place to enter a 3 dimensional function.
Ensure that your equations are in the form z as a function of x and y. Enter each one and it will be graphed on the 3D cube with each equation drawn as a different colored surface. my equations here are z=ex-ey in grey and z=sin(x)+cos(y) in purple.
You can use the arrow buttons to rotate your graph. The Range/Zoom button has a lot of options for changing the graph as well.
