Solving Fractions and Quadratics using the TiNSpire – Step by Step

Say your teacher has some fancy fractions to solve for you and you have a volleyball game , play practice and to prepare for the SAT next Saturday. So you take out your TiNspire CX CAS, launch the STEP BY STEP EQUATION SOLVER app from and get a quick lesson on how to solve those fractions…which turns out not too difficult after following the provided steps below:

We select option 5 :

  1. problem:

to get 5/14 . The trick is to multiply the given fractions by the product of their denominators (bottoms) to get a much easier equation to solve.

Here is another one:


It always works!

Quadratic equations can also be solved step by step. Here is one:


Even equations containing only variables can be solved (for x):

Logarithms – Step by Step – using the TiNspire CX CAS

Using the Step by Step Equation Solver at we can solve – step by step – equations involving Logarithms such as


just type it in the top box and view the step by step solution in the bottom box:

Another example using natural logarithm instead of base 10 :

Say we are asked to expand logarithms, we will then use the Algebra Made Easy app at , go to menu option EXPAND, enter our condensed log expression in the top box to view the expanded version as shown below :


Lastly , we are given an expanded logarithmic expression and we are asked to condense. Well, you know what to do: use the Algebra Made Easy app at , go to menu option CONDENSE , enter our expanded log expression in the top box to view the condensed version as shown below :

Cube root, other roots and radicals using the TiNSpire CX CAS

Say you need to find 3 radical 27 , that is to find the cube root of 27. Enter it as:

and it will display as

Similarly, the 4th root of 16 is entered :

and it is displayed as

And the 5th root of x is then entered as

to be displayed as

Nice and simple. In conclusion, radicals and roots can be dealt with using the handy root-function.

Projectile Motion with the TiNspire CX – Step by Step

Here is how to perform Projectile Motion using the TiNspire CX : Launch the Physics Made Easy from and go to the menu option 2: Kinematics – Linear and Rotational as shown below :

Next scroll down to “Projectile At Angle”. This menu option will do step by step analysis of the projectile given initial values such as Angle, Initial Velocity and Initial height.

Here is an example:

Now, if you are to find Initial Speed, Launch Angle etc just scroll further down in the menu as we have those scenarios covered too.

2. Fundamental Theorem of Calculus using the TiNspire – Step by Step

Applying the Fundamental Theorem of Calculus using the TiNspire – Step by Step – can easily be done using Calculus Made Easy at . Here is an example:

Just enter the given function f(t) which is the integrand.

Next, enter the upper bound of the given definite integral.

Then , Calculus Made Easy provides you with the Theorem and also applies it to show the correct answer.

Steps for the computation can be seen below: First the integrand is integrated and evaluated using the given bounds . Lastly, differentiation yields that final answer.

NEW: Newton Method, Cholesky Decomposition, Jacobi Method, Simpson Rule and more using the TiNSpire CX

The Numerics Made Easy app at was updated to also solve the following concepts:

Secant Method to find zeros of a function
Jacobi Method to solve A*X=B
Cholesky Decomposition
Newton Method for Interpolation
Orthogonal Polynomials: Legendre , Hermite, Chebyshev and Leguerre
3-8 Simpson Rule
Newton Cotes

TiNspire : Volume of Solids of Revolution using Disk, Washer and Shell Methods

Computing the Volume of a Solid of Revolution using the TiNspire CX CAS can easily be done – step by step – using the Calculus Made Easy at .

Here is how.

Let’s start with the Disk Method. We just select that option in the menu:

Then this pops up :

Now, enter the given function in the top box and the given interval below. Automatically, the answer will show in the bottom with correct integral setup and the correct answer.

Similarly, when using the Washer Method for two functions we have:

Finally, the Shell method works the same way :

In conclusion, the just like all other Calculus topics finding the Volume of Solids of Revolution using the Disk , Washer and Shell Methods can be done easily using Calculus Made Easy at .

Kuulin koulussa 3 ihmisen ryhmän puhuvan Calculus kurssista miten hän läpäisi kurssinsa sovelluksen, avulla joka näytti kaikki välivaihe ratkaisut.
Luokkakaveri oli puhunut myöskin ohjelmasta, jonka nimi oli Calculus made easy, mikä näytti kuulemma välivaihe ratkaisut.

Yhden matikan kurssin reputtaneena ja toisenkin ehkä myöskin, turhautumiseni matematiikka kolmannen matikan Calculus kurssiin alkoi olemaan stressaavaa.
Päätin ostaa Calculus Made easy ohjelma TI-Nspire CX CAS laskimeen, tämä ohjelman avulla olen onnistunut tekemään kotitehtäviä jotka, ovat olleet haastavia minulle! 
Erittäin hyödyllinen ohjelma niille jotka eivät ole keskiverto tasoa matikan laskemisessa.
