# 7 Math

Calculus Grapher (PhET) (CC BY)

This lab is an interactive plot builder for a function. It would be useful as a simple visualization tool. Great way to show the relationships between functions and derivatives. The kinematics forms drop out right away, and resonance curves are clear.

Curve Fitting (PhET) (CC BY)

First-year statistics. Nice introduction to curve fitting.

Fourier: Making Waves (PhET) (CC BY)

Differential equations. Very good simulator for Fourier waves.

GeoGebra Website (free for non-commercial purposes)

*From GeoGebra’s website:* “GeoGebra is dynamic mathematics software for all levels of education that brings together geometry, algebra, spreadsheets, graphing, statistics, and calculus in one easy-to-use package.” Has a graphing calculator, computer algebra systems (CAS) calculator, and books and activities on many different math subjects. Also see the GeoGebra YouTube channel.

Least-Squares Regression (PhET) (CC BY)

Statistics. Very good simulator for regression.

Plinko Probability (PhET) (CC BY)

Introductory statistics. Can be used to illustrate the value of a big N. *From the PhET website:* “Drop balls through a triangular grid of pegs and see them accumulate in containers. Switch to a histogram view and compare the distribution of balls to an ideal binomial distribution. Adjust the binary probability and develop your knowledge of statistics!”

Trig Tour (PhET) (CC BY)

Precalculus. Good tool for review. *From the PhET website: *“Take a tour of trigonometry using degrees or radians! Look for patterns in the values and on the graph when you change the value of theta. Compare the graphs of sine, cosine, and tangent.”

Statistics. Contains a guide that introduces and explains the *t*-test, as well as an application for applying it. Requires a free Open University account.
