Step by Step Math & Science & Finance using the TiNspire CX

Using the Differential Equations Made Easy APP at https://tinspireapps.com/?a=deqme you can solve Differential Equations using LaPlace Transforms as shown below:

**Laplace transform over Piecewise def. Function**

Example:

f(1) = 3 defined over 0<= t <2

f(2) = t defined over t >= 2

To find the LaPlace Transform use Differential Equations Made Easy at

https://www.tinspireapps.com/?a=DEQME and select LAPLACE TRANSFORM OF PIECEWISE DEFINED FUNCTION and enter as follows:

We use infinity since the function f2 is not bounded. If it was bounded by for example 10 then we would have entered as [0,2,10]

Auxiliary Equation Solution using the Tinspire CX

Finding the Solution given Auxiliary (also called Characteristic) Equation of a Differential Equation is a fun exercise using the Differential Equation Made Easy app .

Just select option 5 :

Then enter the auxiliary equation (of any order) as shown below

The Differential Equation Solver using the TiNspire provides Step by Step solutions. Launch the Differential Equations Made Easy app at www.Tinspireapps.com . 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.

Below find a bunch of Laplace and Inverse Laplace Transform examples

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:
