Which matrix represents rotation about Origin through 90° in anticloc

1.	Which matrix represents rotation about Origin through 90° in anticlock wise di rection.
Answer» Answer: Rotation MATRICES are square matrices, with real entries. More SPECIFICALLY, they can be characterized as ORTHOGONAL matrices with determinant 1; that is, a square MATRIX R is a rotation matrix if and only if RT = R−1 and DET R = 1.
