Exploring Partial Derivatives with Graphical Illustrator
Given the graph of f(x,y) = sin x. a. Slide x. Describe the relationship between and the graph. b. Check Illustration . Then slide x and y. Describe the relationship between and the graph.
TO EXPLORE IN GEOGEBRA AUGMENTED REALITY:
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.
