orthogonal

Orthogonal basically means independent. But the real meaning is rightangle which came from Greek words orthos(right) gon(angled). The term has been extended to general use, meaning the characteristic of being independent. Two vectors are orthogonal when their dot product is zero, which gave rise a generalization of two vectors on some inner product space being orthogonal when their inner product is zero.

Define what orthogonality is and why it is important.

Explain what do these two movies have to do with orthogonility? media type="file" key="gravity.mpg"This movie shows orthogonality because one ball (on the left) has acceleration in one direction which is down and the other ball (on the right) has not only acceleration in the -y axis but also in the positive x axis. this means that it has two accelerations in different directions; and that would be the definition of orthogonality. -longboardlarry media type="file" key="2dmotion_monkeydrop.mpg"
