Suppose we want to sketch the graph from -3 to 8.

- Enter by pressing “Math, Piecewise”.

2. Adjust the window setting to the required domain.

3. Trace the end point at -3 since it is not 1 complete cycle.

The following comparison are based on

TI 84 CE: Operating system 5.3.0

TI 84 Plus C: Operating system 4.2

Singapore Approved Operating System

**Division of complex numbers**in TI 84 Plus CE can be entered in fractions, whereas it must be entered using division in TI 84 Plus C

.

**Piecewise function**is now available in TI 84 Plus CE. This command can be found under MATH B: piecewise ( . Piecewise function can also be created manually in TI 84 Plus C but slightly more tedious.

New CONDITIONS submenu in “2nd test” allows faster entry of intervals for the piecewise functions

- Inverse binomial distribution and inverse norm enhancement in TI 84 CE

- Store tangent and faster access to n/d template in TI 84 CE

**Conclusion**

There are no major functional differences between TI 84 Plus CE and TI 84 Plus C. For piecewise functions, students should learn how to sketch manually without using the GC.

This question from 2008 alevel, 10iv illustrates the common error in Permutation and Combination.
