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):

▷Differential Equation Solver for the TiNspire CAS – Step by Step

The Differential Equation Solver using the TiNspire provides Step by Step solutions. Launch the Differential Equations Made Easy app at . Here are 2 examples:

1. Solve a 2. order non-homogeneous Differential Equation using the Variation of Parameter method. Just enter the DEQ and optionally the initial conditions as shown below. First, the solution to the homogeneous Diff Eqn is found using the characteristic equation.

Next , the general solution is found by means of Variation of Parameters is found, and every step along the way is shown:


2. Solve a 3. order homogeneous Differential Equation. Just enter the DEQ and optionally the initial conditions as shown below. Again, the solution to the homogeneous Diff Eqn. is found using its characteristic equation.

Lastly, the Initial Conditions are used to find the Particular Solution. See below.



Laplace Transforms and Inverse using the TiNspire CX – Step by Step

Below find a bunch of Laplace and Inverse Laplace Transform examples

using the TiNspire CX CAS  and Differential Equations Made Easy at :


Here we are using the Integral definition of the Laplace Transform to find solutions.

It takes a TiNspire CX CAS to perform those integrations.



Examples of Inverse Laplace Transforms, again using Integration:
