## VIDEO: Periodic Table of Elements using the TiNspire

Hi guys! If you need to view information of the elements in the periodic table AND

you own a TiNspire then I have GREAT news for you: Finding element information is as easy as pi!

You can either search by Element name, symbol or its atomic number. See below: We even have a video on this for you here :

## Statistics Made Easy for the TiNspire update: Inverse Binomial Distribution Solver

## Factoring Using Algebra Made Easy with the TiNspire CAS CX

Factoring expressions, functions and integers can be done easily using Algebra Made Easy on your handy TiNspire CAS CX . The bottom image shows that you enter can any expression which will be factored , you could even enter an integer such as 500 to get 4*5^3 .

Additionally , using the option 1: Algebra then option 8: Find GCD and LCM (Greatest Common Divisor and Least Common Multiple) it finds exactly that – Step by Step . For example, using integers 60 and 75 , we factor those two integers first to then use their COMMON factors for GCD and LCM .

As a side product you learn that GCD*LCM=Integer1*Integer2

Remember that you dont have to press ENTER , just observe how the answers change immediately as the input changes.

## Balancing a chemical equation using the TInspire CAS CX and the Chemistry Made Easy app – step by step

Here is a solved example:

When balancing the chemical equation: Fe2S3+O2=Fe2O3+SO2

The setup is a_*Fe2S3+b_*O2=c_*Fe2O3+d_*SO2

or : a_*(2Fe+3S)+b_*(2O)=c_*(2Fe+3O)+d_*(1S+2O)

This sets up : 2*a_=2*c_ and 3*a_=d_ and 2*b_=3*c_+2*d_

which has the solution : {a_,b_,c_,d_}={2,9,2,6}
