Finding the Equation of a Tangent Line Using a Derivative

[froggaman]

this helps so much. I've told my entire AP calculus class about you. We have a wonderful teacher who, like you, is trying his hardest to get us to actually understand WHY the math works. However, you make the process alot gentler :) I am now confident that i'll rock my test tomorrow. Thanks so much.

Dude, your explanations are the best. You put the information I wanted in a very nicely compressed video. I have horrible ADHD and watching a 9:50 video from Khan academy just further confuses me, but yours and it instantly clicks.

Your explanations are amazing! I try to tell all my classmates about you. Your videos have helped me to get to calculus!

turn down the sound and voilà, you have your wish!

Oh my. Thank you so much, I was getting so worked up over these stupid HW problems.

That's just exactly what I need! Many other math tutorials go all around the subject and back again, totally confusing but this rocks!

How to find the equation of a tangent line if Y is not given?

[David-uunl]

Isnt the equation y = m(x-x1) + y better?
