Eigenvalues and Eigenvectors

Hello,

What is the reason for these two different results?
(The result with Mathcad function is good)
But I think, if I am not making a mistake in the first approach, both results should be identical.

So, what am I missing, or what am I doing wrong?

Mathcad also considers the case that theta is an integer multiple of pi.

You must also be aware that on contrary to the eigenvalues, the eigenvectors are not unique.

You can see this if you compare the numeric and the symbolic result of "eigenvecs([n x n - matrix]))".

The simplest way to proceed is the following:
