What you can do with a CG20
PLOT and SOLVE GRAPHS
Plot any graph in Cartesian (rectangular), parametric and polar form. Find the coordinates of roots, turning points and intersections easily.
Evaluate the derivative at a point. Draw the tangent and normal to the curve, showing the equation. Evaluate integrals and show the shaded area.
Quickly create box plots, pie charts, histograms, scatter graphs and more. Plot regressions (linear, log-lin and a lot more). Import data for plotting and calculating statistics and regressions.
Calculate Normal, Binomial, Poisson and t-distributions between values, and chi-square goodness of fit . Visualise continuous distributions (including Normal) as a graph, shading chosen probability.
Set variable coefficients on functions to explore the effects of single and combined transformations.
