Hi,
I am trying to perform a very simple matrix multiplication:
a01 = {{1, 0, 0, 0}, {0, Cos[20], -Sin[
20], 1.5}, {0, Sin[20], Cos[20], 0}, {0, 0, 0, 1}}
a12 = {{Cos[-60], -Sin[-60], 0, 0}, {Sin[-60], Cos[-60], 0, 1}, {0, 0,
1, 0}, {0, 0, 0, 1}} // MatrixForm
a01 . a12
However, Mathematica will not simplify the two matrixes by combining them into one matrix. I tried all the built in simplication functions but to no avail. My goal is not to have Mathematica evaluate the trig functions but simply combine the two matrices.
Thanks,
Evan
