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. Available in Thai, English, Simplified Chinese, Korean and Japanese. Works offline with no account, ads or in-app purchases. One purchase includes all features. AUTOMATIC CALCULATIONS Choose from 51 topics in 7 categories. Start with a blank notebook, place or drag points, or enter equations and parameters for the selected topic. See the results update and copy your workspace with graphs, handwriting and equations as an image for compatible note apps.
