: Introduction and differentiation of functions such as
Students often forget when to plug in numbers. Rule of thumb from Feliciano and Uy: Differentiate first, then substitute. If you plug in values before differentiating, you will treat variables as constants and miss important terms. If you share with third parties, their policies apply
Plug in known values after differentiation. Never substitute static numbers before differentiating. 4. Maximum and Minimum Values (Optimization)
