RD-62 Rational-Duplex
Calculate on a virtual slide rule
About the app
Virtual pocket slide rule with a geometry face and an algebra face, worked by dragging the slide and a red hairline across the scales. A reading panel lists the value under the hairline on every scale, and presets show multiplication, division, cubes and quadrance. The builder says it follows Wildberger's rational trigonometry, using quadrance and spread instead of square roots, and plate artwork exports as SVG or DXF. Built with Grok.
