How Reciprocating Linear Motion Actually Works! 🤯 (3D vs. Real)

Professor V 👩‍🏫 on Instagram: "🤔 What is the Gradient?? Here’s a quick snippet from my full video breaking down the gradient — the generalized derivative for functions of several variables. It’s the vector of partial derivatives that points in the direction of steepest increase and whose length gives the maximum rate of change. Want the full breakdown with worked examples? Watch it now on my YouTube channel Math with Professor V (link in bio). 💛 Save this for your next exam review! ⸻ #WhatIs

How did no one teach us this in school? This might be the most overachieving letter in the alphabet. #thanksgiving #howtodraw #lineart

Science Subtlety on Instagram: "Parent functions are the simplest forms of functions that serve as the foundation for entire families of related functions. Each one represents a core behavior without any transformations. A linear parent function creates a straight line and shows constant change. A quadratic parent function forms a symmetrical curve that opens upward. A cubic parent function produces a smooth curve that changes direction once. An absolute value function creates a sharp V shape by
