- 2D Geometry Kalkulator (Area & Perimeter: Rectangle, Circle, Triangle, Trapezoid, Regular Polygon)
Quickly compute area and perimeter for rectangles, circles, triangles, trapezoids, and regular polygons.
- 2D Graphing Kalkulator — plot up to 3 functions with intersection & extrema steps
Plot up to three functions, detect x-intercepts, intersections, and extrema via bisection and numeric derivatives. Includes zoom, pan, shareable URLs, and transparent step logs.
- 3D Geometry Kalkulator (Sphere, Cylinder, Cone, Prism)
Compute volume and surface area for spheres, cylinders, cones, rectangular and regular prisms—with unit controls and a shareable result link.
- CI & Hypothesis Test Wizard (Means & Proportions)
Build confidence intervals and hypothesis tests for means and proportions. Supports Welch, paired, Wilson, Newcombe, and visualises p-values.
- Complex Number Kalkulator — a+bi ↔ polar with steps
Convert between a+bi and r∠θ, perform complex addition, subtraction, multiplication, division, powers, and list n-th roots with a live Argand plot and step-by-step breakdown.
- Conic Sections Explorer — standard form, focus, directrix & eccentricity (with steps)
Classify a general quadratic, rotate to eliminate xy, complete the square to standard form, and visualize focus, directrix, and asymptotes. LaTeX/URL/CSV ready.
