How to rotate the positions of a matrix by 90 degrees

WebSep 8, 2024 · This equation determines the curve that corresponds to the rotation of the function f by θ degrees. Simple and beautiful. Examples In the case of the above example where f (x) = x², let’s try to rotate this function by 90° clockwise, that is, by θ = -90° counterclockwise. Then cos (θ) = 0 and sin (θ) = -1 and we get: x = f (-y) = y². WebIt goes back to the unit circle where 0 degrees is along the positive x axis. All our angles greater than 0 and less than 90 (positive y axis) are in the first quadrant (positive x, positive y), so this is that counterclockwise rotation. 1 comment ( 15 votes) Upvote Downvote Flag more Daniel Eitan 3 years ago
