Calculator 570 ex 991 ex - Fraction calculator fx

Une des calculatrices les plus puissantes, un affichage naturel et des fonctions mathématiques complètes.

As a user of calculator 991 ex 570ex, I am confident that the 991 EX 570ex is quite possibly the best classroom calculator they have ever produced.

Aimed squarely at the Secondary school, this would be the calculator 991 ex 570ex of choice for any student. The favorite calculator for student. Complete calculator for high school and university student.

Some of the new features:

NUMBER

See answers in textbook style with fractions, brackets, surd (roots), or any combination.

The new Random Integer function makes it easy to simulate

Factorising large numbers into powers of prime factors with a single FACT command.

ALGEBRA

Solve equations and systems of equations or inequalities. The calculator will solve algebraically any polynomial equation up to 4th degree (quartics). It can find a root for any general equation.

Similarly systems of simultaneous equations now go up to four equations in four unknowns. Also, by using the Inequality function on a quadratic, cubic or quartic polynomial.

MATRICES

Matrices can now be input up to 5 x 5, with the calculator 991 ex 570ex happily finding determinants, sums, products and even inverses.

STATISTICS

Statistical tables - Binomial, Poisson and even Normal distributions are now covered completely. For example, one can calculate the probability that three coins out of five will show Heads; the probability that a person is taller than two standard deviations from the mean; a two-tailed 95% Normal confidence interval. All with a few taps - just entering the values and reading off the result. 
Note to CASIO - add in Chi-Squared values and you will have all the lab scientists and social scientists queueing up as well!
