Y-Axis 3D Rotation Matrix Calculator
Calculate and visualize the 3D rotation matrix around the Y-axis. Input angle in degrees or radians for instant matrix generation and 3D rotation preview.
Rotation Matrix (Y-axis)
$$ R_y(\theta) = \begin{pmatrix} \cos(\theta) & 0 & \sin(\theta) \\ 0 & 1 & 0 \\ -\sin(\theta) & 0 & \cos(\theta) \end{pmatrix} $$
