▷Orthogonal Projection of v onto u1,u2 using the TiNSpire – Linear Algebra Made Easy

Say you need to find the orthogonal projection of v onto W the subspace of R^3  .

You pull out your TiNspire and launch the Linear Algebra Made Easy app from www.ti-nspire-cx.com and enter as follows:


Now, just lean back and view the steps

until the final answer shows. Sweet!


Linear Algebra Made Easy is incredible & enjoyable

User feedback today:

The step by step matrix operations, such as Row Echelon, Gauss Elimination etc are incredible

It is very easy to use;

I like the layout and on the Ti-spire since the processor is faster than the 89 it just makes it more enjoyable to use.

My linear algebra professor does allow us to use a CAS calculator and with the Ti-nspire cx CAS with your linear algebra app… Lets just say my fellow students and professor will be amazed with my knowledge and wisdom… and of course the speed at which I solve matrix operations and systems.
