# Understanding the Definition of the Derivative

Thanks to all of you who support me on Patreon. You da real mvps! \$1 per month helps!! 🙂 https://www.patreon.com/patrickjmt !! Understanding the Definition of the Derivative – In this video, I produce the definition of the derivative by thinking about slopes of tangent lines!
I DO NOT use the definition of the derivative to actually calculate the derivative, although I have videos on that too!!
