Partial Derivatives: Graphical Illustrator

You can enter your own multivariable function in the input box at bottom right. To explore in Augmented Reality, see the directions below the applet.


1) Open up GeoGebra 3D app on your device. 2) Go to MENU (3 horizontal bars in upper left hand corner). 3) Select OPEN. Under search, type: fgzyyx8x 4) The sliders a & b control the x & y coordinates of the point (respectively). You will also see FILLING sliders to fill in the surface itself or the tangent plane. 5) To switch from partial derivative with respect to x and partial derivative with respect to y, adjust the slider named whichpartialderiv at the bottom of the algebra pane.
