How to multiply two matrices without numeric values

How to multiply two matrices without numeric values

How to multiply two matrices without numeric values

(OP)
I need to multiply a couple of matrices that don't have numeric values
e.g: A has a1 a2 on line one and a3 a4 on line two
     B has b1 b2 on line one and b3 b4 on line two
values are rotation angles but there is no specified value
how can i do this using mathcad 13?

RE: How to multiply two matrices without numeric values

Is this for school?  If you have no numeric values, then you should be using the symbolic processor.

RE: How to multiply two matrices without numeric values

You could do it like this:

    (a1 a2)  (b1 b2)
           *         -->
    (a3 a4)  (b3 b4)

obviously written Mathcad style.
