Approximations or exact values — why not both?

TI-Nspire™ CAS (Computer Algebra System) technology provides you and your students the ability to perform both symbolic and standard numeric calculations.

The comparison screens below show step-by-step, arithmetic, algebraic and calculus calculations as they would be displayed on the TI-Nspire™ CAS handheld and TI-Nspire™ handheld.

TI-Nspire™ CAS and TI-Nspire™ handhelds share almost all of the same enhanced graphing and computer feature functionality. The CAS engine is built into the TI-Nspire™ CAS handhelds and Teacher and Student Software exclusively.

Step-by-Step Calculations

prod-nspire-compare-cas-cas1
View exact and approximate values of solutions to an equation.
prod-nspire-compare-cas-noncas1
An error will display without a defined variable to continue the problem.

Arithmetic Calculations

prod-nspire-compare-cas-cas3
Simplified expressions keep their mathematical structure.

Mathematical constants and variables are recognized and simplified symbolically.
prod-nspire-compare-cas-noncas2
Simplified expressions are approxiamted in decimal form.

Mathematical constants (n, e)and variables(x, y) provide approximate numeric answers.
