The effect of the rotation is the same as that of a 90 degree clockwise rotation.
In matrix notation, it is equivalent to [post-]multiplication by the 2x2 matrix:
{ 0 1 }
{-1 0 }

What is the symbolic rule for a 45 degree rotation clockwise around the origin?
(x; y) --> (x.cos45 + y.sin45; x.sin45 - y.cos45)
Rule for 90 degree clockwise rotation?
we swap the co-ordinates and give the new y co-ordinate the opposite sign.90 degrees clockwise(y, -x)
What rule represents a 270 clockwise rotation about the origin?
270 rule represent a 270 rotation to the left which is very easy
What do you think the mapping rule is for a rotation of 270 degrees clockwise?
It is multiplication by the 2x2 matrix 0 1-1 0
What is the rule for a 360 degree rotation?
Very simple. Do nothing!Very simple. Do nothing!Very simple. Do nothing!Very simple. Do nothing!
Rule for 180 degree clockwise rotation?
change the sign, but DONT switch the coordinates (:

What is the rule for a 270 degree clockwise rotation?
(x,y) to (x,-y). You would keep the x the same, but turn the y negative. This is actually the rule for a 90 degree counterclockwise rotation, but they're the same thing, they would go to the same coordinates.

How do you find 270 degree clockwise rotation?

plz awnser this
What is the rule for a 180 degree counterclockwise rotation?
First of all, if the rotation is 180 degrees then there is no difference clockwise and anti-clockwise so the inclusion of clockwise in the question is redundant. In terms of the coordinate plane, the signs of all coordinates are switched: from + to - and from - to +. So (2, 3) becomes (-2, -3), (-2, 3) becomes (2, -3), (2, -3) becomes (-2, 3) and (-2, -3) becomes (2, 3).

Does earth spin counter clockwise?
Almost all of the material that formed the Solar system revolved around the Sun in one direction. This represents the conservation of angular momentum when the material contracted to form the Sun and its planetary disk. Since then, collisions and localized gravity have created exceptions to the general counter-clockwise rule (Venus spins slowly clockwise on its axis). The Earth rotates (spins) on its axis counter-clockwise, and orbits the Sun counter-clockwise as well, as viewed from the North Pole of the Earth or Sun. These are arbitrary concepts of "above" and "below" the plane of the Solar System. The Moon also revolves around the Earth counter-clockwise.

When passing food at the table is it passed from the right side or the left?
Clockwise. However it is really up to the hosts, discretion. ( I mean if the person is sitting one place in the counter clockwise position in no way should you go the whole way around the table (clockwise) first to reach him. ) Also the clockwise rule only applies to the inital serving.
