An interactive collection of calculus and visual math tools. Explore animated lessons, 3D integral visualizers, and graph-first experiences designed to make concepts click fast.
See how position, velocity, and acceleration relate through synchronized graphs, particle motion along a line, and tangent-based intuition.
Open site →Explore solids of revolution with cylindrical shells, adjustable functions, and a visual connection between the integral and the geometry.
Open site →Build solids from a base region and see how squares, semicircles, triangles, and rectangles produce different volume formulas.
Open site →Show amplitude, phase shift, frequency, and vertical shifts with live graphs, presets, and student-entered values.
Open site →Watch the y-coordinate of a rotating point on the unit circle become the sine graph, with linked motion, pi-labeled angles, and live values.
Open site →Watch the x-coordinate of a rotating point on the unit circle become the cosine graph, with linked motion, pi-labeled angles, and live values.
Open site →See how tangent comes from the tangent line and the ratio sin(θ)/cos(θ), with asymptotes, linked geometry, and a live tangent graph.
Open site →Adjust the base and compare y = b^x with y = log_b(x), seeing both graphs reflect across y = x as growth and decay change.
Open site →Explore reciprocal trig transformations with live asymptotes, phase shifts, stretches, and vertical moves for secant, cosecant, and cotangent.
Open site →Restrict sine, cosine, and tangent to one-to-one branches, reflect across y = x, and see how inverse trig domains and ranges are created.
Open site →Practice principal-angle answers for arcsin, arccos, and arctan with unit-circle visuals, exact values, and composition examples like arcsin(cos 100°).
Open site →Solve trig equations with reference angles, quadrant logic, highlighted unit-circle solutions, and quick practice checks.
Open site →Explore reciprocal, Pythagorean, and sum/difference identities with unit-circle visuals, interactive sliders, and worked example problems.
Open site →Use a browser-based TI-84 style graphing calculator for functions, tables, statistics, matrices, and classroom math practice.
