Example

3, 5 gives Trace 8.

Formula

trace = a + d

Add the entries on the main diagonal of the 2x2 matrix.

For a 2x2 matrix, the trace uses only the top-left and bottom-right entries.

Check

Mixing units, scales, or coordinate conventions across a, d before calculating trace.
Confirm that all inputs use the same unit system expected by the formula.
