The Made Easy Apps have helped me while I was taking electrical engineering courses up until May 2010.

It does not matter what field of engineering one is in.

They are very helpful all around.

I was using apps on the TI 89 Titanium and now am using the TiNSpire – they worked great.

## Step by Step Engineering Mathematics using the Ti-NSpire CAS CX calculator program

Attention Engineers with a TI-Nspire CAS CX :

Engineering Mathematics has become much easier : this Step by Step Ti-nspire app covers Math Topics for Engineers (i.e. FE Exam) such as Algebra, Complex Numbers, Conics, Trigonometry, Exponential and Logarithmic Functions, Calculus, Differential Equations with LaPlace Transforms, Statistics, Probability, Combinations & Permutations, Matrices and Vectors. Read Definitions & Theories.  For more details visit: http://www.tinspireapps.com/?a=EMME
