5 toolsPolar coordinates, parabolas, and coordinate system calculators. Browse our free coordinate geometry (advanced) tools below — no sign-up required.
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.
