using the TiNspire’s Statistics Made Easy.

Here is problem that calls for a 2 sided Ztest with given Std Deviation:

Using the Z-test, select the 2 sided test (not equal symbol) at the 5 % level and

entering the 4 values pertaining to the test as shown below:

We immediately see the computed p-value and the drawn conclusion (here we fail to reject Ho as the p value larger than 5%)

Besides Significance Tests the Statistics Made Easy is really useful when

performing Confidence Intervals and also Non Parametric Test available at

If you are to compute the area under the Standard Normalcurve as shown in the problems in the image below:

Just navigate to Normaldistribution in the Menu :

Now enter mean = 1 and std deviation = 0 as we are dealing with the StandardNormal Distribution.

Next enter B as shown given in problem .88 and A can be any number below -3 … out comes the answer

Alternatively, you could have entered .88 for A and found the answer in the 3. line instead of the 2. line

Additionally, InvNorm type problems (given area find z value ) can also be solved

]]>a) PSE

b) Quantum numbers and

c) Polyatomic Ions

using the TiNspire’s Chemistry Made Easy app.

To access the latest Periodic System of Elements from the MAIN menu you have 2 options:

- You can find your element by entering its symbol.

Below you see how we searched for Helium, we entered “He”

Alternatively we could have entered the Atomic Number 2.

All Element Information are displayed and you can easily scroll up and down.

We recently added each elements’ Quantum Numbers.

2) Alternatively you can search by element name.

Below we searched for Iron, so we just typed in.

This is great for elements whose symbol may have slipped your mind, Fe it is here.

3) Polyatomic Ions can be looked up as well, they are sorted by charge for easy navigation.

These and many other features are available in

1) LaPlace and Inverse LaPlace Transforms

View some examples here:

2) Fourier and Inverse Fourier Transforms

3) Fourier Series

You can also look up the following Transforms as reference tables:

LaPlace and Inverse LaPlace Transforms

Fourier and Inverse Fourier Transforms

Z Transforms and Inverse Z Transforms (the apps only offers table look ups but no computations.)

Below’s screenshot gives an idea of the Transforms and its uses.

Additionally, 2. order Differential Equations can be solved using LaPlace Transforms – step by step.

]]>Determinants of 2×2 and 3×3 matrices can simply be computed using their set formulas as seen below:

Determinants of 4×4 and higher matrices actually take advantage of determinants found for smaller square matrices using Cofactors as illustated below. As usual, nicely laid out with every step along the way until the final answer shows.

]]>perform Integration using U-Substitution.

The first way is the fully automated: Just plug in your given function as seen below and steps and answer are displayed.

The second way requires your input on the choice of u. You may wonder what is

point if the fully automated version can do this already? It is called LEARNING:

U Substitutions are not unique: Different choices of U may lead to the same solution.

Check out below’s example:

Check out another choice of U, it leads to the same solution.

Our Made Easy APPS aim at empowering students and this feature allows you guys to

learn about U-Substitution in a way you likely will not in your classroom. So enjoy this feature.

As usual, updates are free forever.

]]>This is what you need to do to get connected:

- Uninstall TI Connect v4.0 if installed.
- Download and Install TI Connect version 4.1 : https://education.ti.com/ticonnect/ticonnectmac41 . Beware: this link immediately downloads the .dmg file to your MAC, there is no webpage loading. Note: that download link may change if TI places the link on a webpage instead.
- Make sure that you do not have a USB cable connected to your computer WHILE installing TI Connect.
- If Ti89 is not recognized by your MAC: restart the MAC, try the other USB ports, have patience as drivers may take time to load. Listen carefully for sounds signaling successful driver installation.
