#derivatives — Public Fediverse posts

The fancy vocabulary of finance is efficient once you learn the lingo, but the actual foundation is built on concepts you already use every day https://hackernoon.com/a-derivative-is-just-a-function #derivatives

Softmax, can you derive the Jacobian? And should you care?

Alright, future engineers!
A **Derivative** measures the instantaneous rate of change of a function or the slope of its tangent line.
Ex: Power Rule: `d/dx (x^n) = n*x^(n-1)` (e.g., `d/dx(x^3) = 3x^2`).
Pro-Tip: Think 'slope'! It tells you how fast something is changing *at that exact moment*.

Ah, another riveting revelation that "areas" need definitions! 🤔 This mind-blowing journey through #rectangles and partitions will surely redefine your life—assuming, of course, that you've never heard of #calculus before. 🙄 Bravo for connecting #integrals and #derivatives, an insight only centuries old! 🎉

Alright, future engineers!
**The Chain Rule** helps differentiate composite functions (functions within functions).
Ex: If `y = sin(x^2)`, then `y' = cos(x^2) * 2x`.
Pro-Tip: Derivative of the outside, times derivative of the inside!

Alright, future engineers!
The **Derivative** `f'(x)` is the instantaneous rate of change of a function, or the slope of its tangent line. Ex: If `f(x)=x^3`, `f'(x)=3x^2`. Pro-Tip: It's crucial for optimization & understanding how systems respond instantly!

Alright, future engineers!

A **Derivative** is the instantaneous rate of change of a function, or the slope of its tangent line. Ex: For `f(x) = x^2`, `f'(x) = 2x`. Pro-Tip: It's how fast things *are changing* right now!

A **Derivative** measures a function's *instantaneous* rate of change. Ex: `d/dx(x^n) = nx^(n-1)`. Pro-Tip: Think slope of the tangent line! It's crucial for analyzing motion, rates, & optimization.
#Calculus #Derivatives #STEM #StudyNotes

The derivative measures a function's instantaneous rate of change (its slope!). Ex: `d/dx(x^3) = 3x^2`. Pro-Tip: Crucial for optimization – find max/min points when `f'(x)=0`.
#Calculus #Derivatives #STEM #StudyNotes

The derivative measures a function's instantaneous rate of change (slope of tangent). Ex: d/dx(x^n) = nx^(n-1). Pro-Tip: Think slope! For position, its derivative is velocity; for velocity, it's acceleration.

A Brief Course Of Higher Mathematics by V.A. Kudryavtsev

The aim of this text is to set forth the essentials of higher mathematics and their applications in various fields. At present higher mathematics serves as the theoretical foundation for most branches of the natural, applied and engineering sciences. Therefore, every natural scientist must necessarily master its methods to be able to apply them for practical purposes.
