สรุป	Inverse kinematics is the computational problem of determining the joint angles required to position and orient the end-effector (tool) of an articulated mechanism at a desired pose (position and orientation). In contrast to forward kinematics, which computes end-effector position from joint angles, inverse kinematics solves the reverse mapping. This is essential for robot control: given a desired target location, IK finds the joint commands that achieve it.	Modal analysis is a computational and experimental method for determining the natural frequencies and associated mode shapes of a mechanical structure. By decomposing structural vibration into its fundamental modes (natural oscillation patterns), engineers can predict resonance frequencies, assess dynamic response to external forces, and design structures to avoid problematic vibrations. Developed rigorously by Clough and Penzien in their foundational work on structural dynamics, modal analysis is essential for designing robust mechanical systems.
