Start from a real construction.

Each card opens a real construction in Graphing or Geometry — click any point and drag it. Nothing is saved to an account, so you can experiment freely.

Parabola and lineA quadratic, a line and their intersections — drag nothing, just read the graph.Open in Graphing Sine and cosineTwo periodic functions, plus the shaded region where y < sin(x).Open in Graphing Roots and extremaA cubic with its roots and turning points found for you.Open in Graphing Area under a curveThe definite integral of x² from 0 to 2, shaded on the graph.Open in Graphing Statistics from a listA small data set with its mean, median and standard deviation.Open in Graphing Triangle centroidMedians of a triangle meet at the centroid; the circle passes through the vertices.Open in Geometry Tangent to a circleA point on a circle, its tangent line and the radius to the contact point.Open in Geometry Unit circle and angleA circle of radius 1, an angle on it, and the triangle that shows sine and cosine.Open in Geometry
