Absolutely brilliant explanation and visualization. Amazing that you got it all in 60 seconds

[@actual.education]

Thanks! Yeah kids' attention spans aren't what they used to be - so I try to get to the point as quickly as possible.

[@clutchys3276]

Hoooly that's why. Thank you. I never comment on videos but this was actually helpful.

[@actual.education]

Glad it made some sense! Yeah it's really dumb how some teachers don't show the graphical explanation for what all the fancy limit stuff is

[@t-rex5439]

As a student who is just starting calculus, this is really helpful! Keep it up!

[@actual.education]

Awesome man! Good luck with calculus - one of my fav classes - I have a couple videos on later concepts as you get to them!

Why is the line between point a & point b called the secant line when the points are farther away?

[@actual.education]

The line between points a and b is always the secant line, but as b gets closer to a (like right on top of it) that secant line is basically the same as the tangent line. Technically the tangent line only touches the function at one point.

But wasn't that first principle of differentiation like that also givess us the answer

[@actual.education]

Yep! I show that in Pt 2 😊
