 InterpolatePy implements several key mathematical concepts for trajectory generation:
 
 ### B-splines
+
 Piecewise parametric curves defined by control points and a knot vector. B-splines offer local control (changes to a control point only affect the curve locally) and customizable continuity.
 
 ### Cubic Splines
+
 Piecewise polynomials with C² continuity (continuous position, velocity, and acceleration) that interpolate a given set of points.
 
-### Smoothing Splines 
+### Smoothing Splines
+
 Splines with a controllable balance between accuracy (passing through points exactly) and smoothness (minimizing curvature). The μ parameter controls this tradeoff.
 
 ### Trapezoidal Velocity Profiles
+
 Trajectories with linear segments of constant acceleration and velocity, creating a trapezoidal shape in the velocity profile.
 
 ### Double-S Trajectories
+
 Motion profiles with bounded jerk, acceleration, and velocity, creating smooth S-curves in the acceleration profile. These are ideal for robotic motion to reduce stress on mechanical systems.
 
 ### Frenet Frames
+
 Local coordinate systems defined by tangent, normal, and binormal vectors along a curve, useful for tool orientation and trajectory tracking.
