The interactive science learner
toolbox.
Move beyond a result: change a model and watch its behaviour.
8 useful places to start.
These are stated mathematical models with numerical limits, rather than measurements or experimental predictions.
Interactive function plotter
Graph up to three expressions, zoom the viewport and inspect values along the X axis.
Interactive pendulum simulation
Change a pendulum’s length, gravity and damping, then watch its motion and angle trace.
3D vector calculator
Calculate lengths, dot and cross products, angle and vector projection.
Small matrix calculator
Add, multiply, transpose, invert or find a determinant for matrices up to 6 × 6.
Triangle from sides & angles
Solve a plane triangle from two sides and their included angle, or one side and two angles.
Circle through three points
Find the circumcentre, radius and equation of the circle through three plane points.
Cartesian & spherical coordinates
Translate 3D Cartesian coordinates and radius/azimuth/polar-angle coordinates.
LC resonance calculator
Calculate an ideal LC resonant frequency and the series-RLC quality factor.
A few things you
can tick off.
- Inspect values on a function graph
- Explore nonlinear and damped motion
- Compare coordinates and geometric constructions
