Why is the sign entered into the rotation matrix for only y-axis rotation different? Since the direction of rotation for only y-axis rotation is different in Direct, is it correct to multiply the angle by -1?
Is this because the coordinate system is inverted when the y-axis is rotated?
cos(θ) 0 sin(θ) 0
0 1 0 0
−sin(θ) 0 cos(θ) 0
0 0 0 1
What is the reason why the sign of sin is different from rotation of other axes?
