Using the Chain (Function of a Function) Rule

[@arctangentart]

Eddie, I have been trying to understand Leibniz notation for about 10 years now. I love math, I like doing recreational math, but it has never made sense to me. Thank you so much for these three videos, I feel like I have a foothold on it now!

The laser point logic of your presentation really stresses how amazing it is to know how many educators that are out there, who have not understood this concept.

I stood up and shouted whoo hoo! that I got that last problem right. Thanks, such a great instructor!

Eddie, you have been such a great help for me, saviour you might even say during year 12. You've inspired me to becoming a teacher and to record my lessons for the world to see. Any support would be greatly appreciated

Bro legit same!!! Best teacher ever

I wish I had a math teacher like this when I was in year 12

leibnez notation is very simple and straight forward and is how we can visually understand the chain rule for taking the derivative of composite functions Ex: dy/dx= dy/du • du/dv • dv/dx where all values cancel except the (dy) in the numerator and the (dx) in the denominator. Very logical and easy to understand. God bless you all!

Thanks to you I’ve done intro to calculus in 1 hour

best explanation I have seen, and love your visual Russian doll props.

What a great teacher

[@JohnM...]

The mnemonic is the 'yuux' rule - said like "yucks" dy/du x du/dx

He said inner function can be anything like that "t" but mathematically speaking that would be incorrect. Just a little thing and it doesn't really matter I guess since I think I knew what he was trying to say but let's just say it was t, then that means we are doing that w respect to x since we using dy/dx and thus dy/dx becomes 0. Lol

[@s4ad0wpi]

This was a common trick question in my Highschool... What's dy/dx if y=3t^2+7

[@defytyrantsofmississippi2198]

@@s4ad0wpi it would have to be dy/dt not dy/dx

[@s4ad0wpi]

Hence: "Trick question" dy/dx = 0 in this example
