In there, he talks about calculating gradient of xTAx and he does that using the concept of exterior derivative. The proof goes as follows: y = xTAx. dy = dxTAx + xTAdx = xT(A + AT)dx (using trace property of matrices) dy = (∇y)Tdx and because the rule is true for all dx. ∇y = xT(A + AT)Words containing J: jo, aji, haj, jab, jag, jam, jar, jaw, jay, jee.

A right angle rotation about X X axis followed by an equal amount of rotation about Y corresponds to an overall effective rotation of 90∘ 90 ∘ about Z axis. So, ij = k i j = k. Similarly, you can physically verify the quaternion multiplication laws. Compute all cross products involving the vectors i, j , and k.
