Thank you. I had been hesitating to make the purchase as I had wanted to get the apps for TI Voyage 200; but I decided to get the ones for TI-Nspire CAS CX instead, basically because it has more memory available. These apps you sell have the potential to become addictive so I most likely will be back for more! I think I made the right choice. So, needless to say, I am very impressed. Beauty is in the eye of the beholder. Your programs are my drug of choice. I am sure to enjoy them for the remainder of my life. They are one of the few things worth buying besides food and a good pair of boots.

## Thank you very much! All set and working…..Great Customer Support!!!!!

Thank you very much! Chemistry Made easy for NSpire all set and working…..

Great Customer Support!!!!!

## I think I’m in love with you guys

I think I’m in love with you guys!!!!!

Just bought Chemistry Made Easy…..

## Impressed with Calculus Made Easy for Ti-Nspire

Hi Mike

I was so impressed with CME that I bought AME and PME and they are both first-rate.

I’ll be buying more as they appear.

Your apps have made the Nspire a lot more useful to me than it was – in fact, I’m beginning to like it quite a lot.

Congratulations on the hard work, I suspect your nspire apps will be even more successful than the Ti89 apps.

Best wishes

## Z-Transforms using the TiNspire CX CAS

We again listened to your request and added Z – Transforms and Inverse Z-Transforms to the Differential Equation Made Easy APP at www.TiNspireApps.com .

Lets take a look at the menu to see the lengthy listing of the forward Z Transforms.

Here is an example of the Z-Transform of an exponential function:

Below find the menu options for the Inverse Z-Transform:

Options A and B offer a Table of Z Transforms and Partial Fraction Decomposition which are useful tools when doing Z Transforms.

## TiNspire: CoFactors , Determinant , A as Product of Elementary Matrices

To Find a Determinant given CoFactors in a Row use Linear Algebra Made Easy at www.TiNspireApps.com and enter your quadratic Matrix and selected Row as follows:

When selecting Row2 we get the following CoFactors and of course the same determinant:

To Express a quadratic Matrix as a Product of Elementary Matrices we simply keep track of the RREF Operations when finding its Inverse Matrix. See below:

and finally

Voila !

## TiNspire CX CAS : Solving 1. order Differential Equations – Step by Step

If we are asked to solve the 1. Order Differential Equation y’+4y=8 we see that it is Linear in y and thus use option B in Differential Equations Made Easy at www.TiNspireApps.com as shown below:

Next enter the coefficients 4 and 8 and leave the 2. box empty since we are not given any initial conditions.

To get the general solution :

If we are given this first order homogeneous Differential Equation :

dy/dx + 5yx^3 = 0 we think of it as dy/dx = – 5yx^3 which calls for Separable Differential Equations which are solved using option 3 as follows :

Here we add an initial condition which allows to find a particular solution:

and finally the separation of variables method yields the particular solution:

## TiNspire CX CAS : Integration by Parts – Step by Step

To perform Integration by Parts just enter the given functions under Step by Step Integration using Calculus Made Easy at www.TinspireApps.com as shown below

Then enter given function and view steps in bottom box

And further:

Another example:

## TiNspire CX : Euler Method (Differential Equations)

When solving a Differential Equation y’=y*(5-y) , y(0)=9 numerically using the Euler Method given stepsize of 0.1 use the Differential Equations made Easy app at www.tinspireapps.com and select Euler Method in the Menu as shown below :

Now you just enter the Differential Equation in the top box and the starting point and the step size in the bottom box as shown below:

The bottom box now shows the step by step solution of the Euler Method. Works correctly for any given Differential Equation.

Alternative to the Euler Method you may also the built-in Runga Kutta RK4 method.
