3D Rotations and Quaternions vs Learn Poisson Binomial Normal

3D Rotations and Quaternions is an interactive tool for users who work with 3D orientation math in graphics, roboticsor simulation. It provides precise computations, clean visualizations, and fast conversions between the standard rotation representations. Features include: • Conversion between Euler angles, axis–angle, quaternions, and rotation matrices • Interactive 3D visualization and rotation animation • Quaternion interpolation (LERP and SLERP) • Rotation of user-defined points by user-defined quaternions • Determination of a quaternion that rotates vector v into vector w • Composition of up to 10 sequential quaternion rotations • Quaternion generation from constant angular velocity and time • Reflection of a point across a plane Feedback and suggestions: graphmath@aol.com

Explore three key probability distributions (Poisson, Binomial, Normal) using hands-on and visual learning! Designed by your friendly neighborhood math instructor of 25 years, this app is classroom tested and student approved. Includes mini-lessons explaining how each works, broken into digestible chunks for tabbing through. With these as background info, exploring with the applets will quickly build a full grasp of what is happening! Got hurricanes making landfall? Customers arriving in a queue? Use Poisson. Rolling twelve dice? Surveying 30 students? Use binomial. Weighing a wombat wandomly [sic] taken from the woods? Use normal. But what kinds of results can you expect, in each case? This app provides the insights! Recommended for students in an introductory statistics course, or any other course where probability distributions are important.
