thank you so much! i kept getting stuck in the part when you can separate the cos and sin with the denominator h (i didn't think about that). :D

Great, just what I needed, a simple quick explanation. THANK YOU!
Godd tutorial! Altough english is not my native language you explain it very clearly and structured. Many thanks!
thank u so much! i was having trouble with the denominators in the numerator and getting rid of h, and this video totally straightened me out! :)
I've been looking for this, thanks! you should make more videos and help alot more people : ]

wow...this is lovely - man u add a new dimension to my view of derivatives!!! thanx a ton!
I like the way you present the topic. It is a lot easier to grasp with the animations and the simple example. Simple and effective! :)
Thank you! I have been looking for this everywhere! Everyone is showing examples and all I wanted was a list of what is the derivative of what. THANKS!
