CG20

CASIO CG20

The fx-CG20 has been replaced by the fx-CG50

The fx-CG20 is an advanced graphic calculator, with natural maths display on a full-colour, high resolution backlit screen. It allows you to plot and analyse graphs and their transformations, import data directly over USB, plot data charts and calculate statistics, calculate and visualise probability distributions, calculate matrix and vector arithmetic, perform complex calculations not possible on a scientific calculator, calculate spreadsheets and recursive sequences. It can be upgraded to display and solve 3D graphs.

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.

cg20

EXPLORE CALCULUS

Evaluate the derivative at a point. Draw the tangent and normal to the curve, showing the equation. Evaluate integrals and show the shaded area.

cg20

DATA

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.

cg20

PROBABILITY

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.

cg20

EXPLORE TRANSFORMATIONS

Set variable coefficients on functions to explore the effects of single and combined transformations.

EVALUATE MATRIC and VECTOR ARITHMETIC

Evaluate matrix arithmetic, including inverses, up to 999 rows or columns. Evaluate vector arithmetic, including scalar and vector products.
