Polar coordinates, parabolas, and coordinate system calculators. Browse our free coordinate geometry (advanced) tools below — all calculators are instant, accurate, and require no sign-up.
Cartesian to Polar Converter — Convert Cartesian (x, y) coordinates to polar (r, θ) and back, with batch mode, coordinate plot, and conversion reference table.
Parabola Calculator — Analyze parabolas in vertex or standard form — find vertex, focus, directrix, axis of symmetry, latus rectum, and x/y-intercepts with interactive graph.
Parallel Line Calculator — Find a parallel line through a point, compute distance between parallel lines, and compare slopes, intercepts, and angles with visualization.
Polar to Cartesian Converter — Convert polar (r, θ) coordinates to Cartesian (x, y) and back, with batch mode, coordinate plot, and complete conversion reference.
Slope Calculator — Calculate slope from two points or slope-intercept form, find angle of inclination, parallel and perpendicular slopes, and graph the line.
