2Dpöörlemismaatriks
2Dpöörlemismaatriks, also known as a 2D rotation matrix, is a fundamental concept in linear algebra and computer graphics. It is a 2x2 matrix used to perform rotations in a two-dimensional space. The general form of a 2D rotation matrix is:
where θ is the angle of rotation in radians. This matrix can be used to rotate a point
[ cos(θ) -sin(θ) ] * [ x ] = [ x' ]
[ sin(θ) cos(θ) ] [ y ] [ y' ]
The resulting coordinates (x', y') represent the new position of the point after rotation. The rotation matrix
