Finding Critical Points on the TiNspire CX CAS – using Calculus Made Easy

Finding Critical Points and also a relative & absolute Minimum or Maximum is easily done using the

Calculus Made Easy APP at www.TiNspireApps.com  . Simply select “Critical Points” in the Menu.

 

Here, you can either enter the given function f(x) in the top box or
enter its given derivative in the bottom box.  We enter f(x) in below’s example.

Then, the derivative f'(x) is computed

and simplified to a more compact expression:

finding its zeros yields the following x values of the critical points.

Since we entered a periodic trigonometric function f(x)
we obtain infinitely many critical points of the format
shown below. Note that n87 represents a constant which
is usually denoted as K in textbooks.

Besides finding critical points, Maximum and Minimum values
you will also be able to find saddle points and inflection points under this menu option.

 

 

TiNspire Integration via U-Substitution Solver – Step by Step – using Calculus Made Easy

Here are great news: Now Calculus Made Easy for the TiNspire CX CAS  offers you two different ways to

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.

Customer lost test anxiety using Made Easy APPS : Laplace, Fourier Transforms with Steps

Customer Testimonial :

Basically, I always struggled with calculus so those steps are essential…

Laplace, Fourier Transforms with Steps have made my life much easier because I can check my errors and I no longer have test anxiety…

The book is sometimes too complicated to understand with all the formulas and variables…

I took linear algebra and got a D and because of your apps I will retake it with all my pearly white showing…#IEEE

 

Find the angle (Theta) between the two vectors using Vector Calculus Made Easy for the Ti-Nspire CX CAS

Say we have to..

Find the angle (Theta) between the two vectors

U= cos(pi/4)i + sin(pi/4)j

V= cos(pi/2)i + sin(pi/2)j

 

When entering these 2 vectors using option 1 6 in Vector Calculus Made Easy we will not use the i-j notation and instead use vector /matrix notation as  shown in this image . The angle is derived using arccos(AB/|A|*|B|) and given in radian format.

 

Note: We know that the vectors differ by an angle of pi/2-pi/4=pi/4 or .785  , which also equals 45 degrees.
