### Binnoy Panicker

Discussion -1] Sin( ) is a measure of how much perpendicular two objects/forces are.

2] Log(effect) = cause,....10^cause = effect.

3] Transpose of a Matrix = Rotation by 180 degrees.

4] i = rotation by 90 degrees,....i^2 = rotation by 180 degrees, i^3 =rotation by 270 degrees.

5] e^(i.any angle) = rotation anticlockwise by that angle.: e^(-i.any angle) =rotation clockwise by that angle.

6] Cos( ) is a measure of how much aligned two forces are.

7] Diagonal of a matrix is its axis of rotation.
