Interactive math visualization tools
Online tools are the Tools layer — math visualizations, calculators, and equation utilities that support Learn Math / Learn Physics when you already know the intent, without defining the whole brand as a tool site.
Quadratic Equation Graphing Tool
Free interactive quadratic equation graphing tool. Drag a, b, and c to explore parabola opening, axis of symmetry, and vertex — for class and self-study.
Open tool page →Linear Function Graphing Tool
Free interactive linear function graphing tool. Adjust slope k and intercept b to see how a line tilts and shifts — ideal for class demos.
Open tool page →Parabola Vertex Form Graphing Tool
Interactive vertex-form parabola tool. Adjust a, h, and k to see how translations move the vertex.
Open tool page →Inverse Proportion Graphing Tool
Free interactive y = k/x graphing tool. Change k to explore hyperbola branches and asymptotes for class or self-study.
Open tool page →Pythagorean Theorem Visualizer
Interactive Pythagorean theorem visualizer. Drag a right triangle’s legs and watch the three squares confirm a² + b² = c² live.
Open tool page →Triangle Angle Sum Visualizer
Drag triangle vertices and verify that interior angles always sum to 180°. Free interactive geometry tool for class intro lessons.
Open tool page →Similar Triangles Visualizer
Explore similar triangles interactively — corresponding angles and proportional sides for geometry class and review.
Open tool page →Circle Area Visualizer
Interactive circle area tool for πr². Change the radius and watch area grow — great for early geometry measurement.
Open tool page →Fraction Bar Visualizer
Understand fractions with an interactive fraction-bar model — whole vs parts for early elementary math.
Open tool page →Percentage Bar Visualizer
Interactive percentage tool linking percents, fractions, and decimals — ideal for early percent lessons.
Open tool page →Sine Wave Graphing Tool
Interactive sine graphing tool. Adjust parameters to see amplitude, period, and phase shift — for high-school trigonometry.
Open tool page →Derivative and Tangent Line Visualizer
See how a tangent line moves along a curve to build intuition for derivatives and instantaneous rate of change.
Open tool page →Coordinate Plane Tool
Interactive coordinate plane for quadrants and ordered pairs — a foundation for graphing linear and quadratic functions.
Open tool page →Unit Circle: sin, cos, tan Visualizer
Drag an angle on the unit circle to see (cos θ, sin θ) and tan θ — ideal for introducing trigonometry.
Open tool page →Riemann Sums: Approximating Area Under a Curve
Interactive left, midpoint, and right Riemann sums — refine partitions to approach a definite integral.
Open tool page →Linear Systems: Intersection of Two Lines
Adjust two line equations and see unique, none, or infinitely many solutions as intersection, parallel, or coincident lines.
Open tool page →Interactive Graph of y = log_a x
Change the base to see increasing vs decreasing logs, and compare with the inverse exponential.
Open tool page →Interactive Ratio Bar for a:b
A bar model for ratios: simplify a:b and see each part as a percent of the whole.
Open tool page →Law of Sines: Circumcircle Proof a = 2R sin A
Circumcircle, chord midpoint, and right triangle OMB — see sin A = (a/2)/R. Toggle to verify the cosine law too.
Open tool page →Sphere: 4πr² Area and (4/3)πr³ Volume
Interactive 3D sphere — change the radius to see surface area, volume, and scaling laws.
Open tool page →Interactive Slope (Direction) Fields
See dy/dx = f(x,y) as tiny slopes on a grid — intuition for differential-equation solution curves.
Open tool page →Shifts & Stretches: a, b, h, k on a Graph
Using y=x², interactively stretch and shift to master y = a f(b(x−h)) + k.
Open tool page →Interactive Factors, Multiples, GCD, and LCM
Highlight all factors of n and compute gcd and lcm of two numbers.
Open tool page →Cylinder πr²h vs Cone (1/3)πr²h
3D comparison: with the same base and height, a cone is one-third of a cylinder.
Open tool page →Piecewise Functions: Different Rules on Each Side
Move the breakpoint and left/right slopes to see continuity and corners.
Open tool page →Inequality Systems: Intersection of Half-Planes
Move two boundary lines and watch the green feasible region for a system of linear inequalities.
Open tool page →Multiplying Decimals with a Tenths Grid
A 10×10 grid for 0.a × 0.b — purple overlap cells are hundredths in the product.
Open tool page →Reduction Formulas on the Unit Circle

FAQ
Tools or topic hubs first?
Prefer math/physics pillars for learning; use tools for direct intents like graphing or writing.
Where is the equation editor?
Tools layer: /latex.html, linked with the symbols sheet.
Are tools free?
Yes — browser-based, no install.
Overlap with the Math hub?
No — hubs teach by topic; tool pages open specific interactives. They cross-link.
