I am trying to calculate rotations without given angles using only the coordinates from one system to the next and then using trigonometric identities to determine the angles.

Yes, you can do that with the Symbolic Toolbox, by using rotation matrices.

However, if you are doing 3D rotations and you know the start coordinates and the end coordinates, then there are always at least two different rotation orders that can be used to get there.

This sounds like it might be an Inverse Kinematics question; see https://www.mathworks.com/products/symbolic/code-examples.html?file=/products/demos/symbolictlbx/humanoid_robot/analytical-solutions-of-the-inverse-kinematics-of-a-humanoid-robot.html
