Rachii Conic

Explore upper-secondary analytic geometry through hands-on experiments.

• Explore slope from two points: drag endpoints or the segment and see live calculations in point–slope and slope–intercept forms. • Snap coordinates to integers, attach points to curves, draw straight ink, erase and use a fading laser pointer. • Search lessons and notebooks, hide the inspector and explore a 3D cone section lab. • Present the workspace on a compatible external display through AirPlay.

• Combine lines, circles, parabolas, ellipses and hyperbolas on one graph. • Adjust position, size and rotation while viewing standard and general equations. • Create real nondegenerate conics from general-form coefficients. • Explore foci, directrices, asymptotes, eccentricity and vertex tangents. • Calculate intersections for line–curve and circle–circle pairs. • Learn with 50 lessons and worked examples, plus 68 practice questions with explanations. • Write on the graph with Apple Pencil on a compatible iPad, or use your finger. • Save notebooks locally and export PNG images, PDF worksheets and editable notebook files.
