In this clip from the Genius by Stephen Hawking video series, learn about Rene Descartes' discoveries concerning the dimensions of length, width, and height.
This tool lets students explore graphs of polynomial functions and approximate tangent lines, derivative curves, and areas. Modify graphs and parameters as you work to see if you can improve your approximations.
This activity shows a representation of three geometric series and the harmonic series. A geometric series is a sum of numbers such that the ratio between consecutive terms is constant.
This virtual pan balance lets students compare algebraic expressions. Weigh and compare the expressions by entering them on either side of the balance. Practice arithmetic and algebraic skills, and investigate the important concept of equivalence.
