Question

Verify using an example that Vector a + (Vector b • Vector c) is not equal to (Vector a + Vector b) • (Vector a +Vector c). (This means that addition does not distribute over the dot product.) Explain the problem that arises.

Answer 1

If the vector A = 2.0i + 3.0j, vector B = 4.0j + 3.0k and vector C = 5.0i ‒5.0k, find the value of (A × B).C
