Polar Grapher – GeoGebra Polar GrapherEdit the first object, initially r (t) = cos (3t), to the polar graph of your choice Grab the angle slider to draw the curve, or right click on the slider and choose "Animation On" Use the scroll wheel to zoom in and out
Slope field plotter – GeoGebra Plot a direction field for a specified differential equation and display particular solutions on it if desired
Surface Plotter in Spherical Coordinates – GeoGebra Plotting the surface in spherical coordinatesYou have two angles in spherical coordinates; and which is the positive angle starting from x axis, on xy plane and is the positive angle starting from z axis This applet includes two angle options for both angle types You can set the angles to create an interval which you would like to see the surface Additionally, spherical coordinates includes
Vector Fields – GeoGebra Explore vector fields interactively with GeoGebra's tools and visualizations
Slope Field Generator – GeoGebra Slope Field generator and approximate solution curves given initial values Credits: Originally created by Chip Rollinson
Parametric equation plotter – GeoGebra Plot the parametric equations [math]x=f(t)[ math], [math]y=g(t)[ math] for some interval [math]t_{min}\\le t \\le t_{max}[ math]
Entering polar coordinates and curves – GeoGebra Entering polar coordinates and curvesPolar coordinates are entered using a semi-colon: e g (3;pi 3) The default angle measure is degrees This can be changed in Settings > Graphing (cubic icon) Polar curves can be entered directly: e g r=3+2cos (θ) NB GeoGebra will plot negative values of r You can also use the command Curve [ (r;θ),θ,start value, end value] e g Curve [ (2 + sin (θ 2
