Several great math tools for high school students and teachers. Use the Graphing Calculator to graph up to 5 equations, finds intersections, can produce table of values. Use the scientific calculator for trig functions, inverses, logs, permutations and combinations. Use the matrix calculator to add, multiply, and transpose matrices and vectors. Use the statistics calculator for both basic statistics – standard deviation, correlation coefficient – and regression analyses,and t-tests.
Navigation for switching from one calculator to another is a bit quirky. You have to reload the page. A big plus for this site, though, is that you can save your work via a url link. Send it to yourself or your teacher. You can revisit the link and continue with the calculations, and revise the link to your updated work.
