Problem with symbolic evaluation

[rgunwaldsen]

I am having a problem obtaining consistent symbolic evaluation.

Toy example in Prime 4.0 worksheet is attached.

Result seems dependent upon both order of multiplicative arguments to sin function and order of symbolic key words.

Not sure what I am missing?

Hmm, one more case where Mathcad 11 & Maple outperform Prime & Mupad:

I wonder how Mathcad 15 with Mupad fare...

Success!

 MC15 seems to make sin arguments consistent;
