Visit http://ilectureonline.com for more math and science lectures! This video is part of an eight 8 part lecture series on derivatives. Different algebraic expressions require different techniques in order to discover their derivation. I encourage you to watch the whole series and familiarize yourself with each technique as calculus is the key to understanding pretty much everything about the world!

Thank you for the video, Prof. I have a question: what if the denominator is the sqrt of x square, for example (3x + 6 - 2)/(sqrt of 5x^2 - 4x - 10)? How to combine the quotient and chain rule in this example?

Where's the final answer?
Dominic Sarmiento (4 months ago)
Michel van Biezen is it 3 multiply to (8x-9) and you will get (24x-9) then after you get it , it will multiply again to the (5x^3 + 2x^2)?
Michel van Biezen (4 months ago)
That is the "final" answer. You can simplify it algebraically, but you will find that different text books will leave the answer in a different form.

I like how prof 👏👏

How do you know when you have your final solution sometimes with these questions?
baldy hardnut (1 year ago)
Thank you for not making me feel like ime wasting my time trying to simplify expressions further.
Michel van Biezen (1 year ago)
That is somewhat arbitrary as you can have your final answer is multiple forms.  The general rule is that you don't have any radicals in the denominator and you try to factor out as much as you can.

god damn these questions are a nightmare at first...?

It's actually very difficult to see what he writes in the board: too small, dark and blurry.

Its perfect for me though
Michel van Biezen (1 year ago)
Yes our older videos are not as clear. You can actually increase the image quality if you are using a computer by increasing the resolution.

This was a huge help. Very straight forward.

Thanks for teaching!!

what about the remaining (5x^3+2x^2) in the numerator that cant be factored out, can you still cancel it out against the denominator making the denominator (5x^3+2x^2)^2 and the numerator (4x^2-3)^2[3(8x-3)-2(15x^2+4x)(4x^2-3x)] ?
Michel van Biezen (2 years ago)
The first step is the important step and there is only one way to use the quotient rule (as shown in the video). Also note the rules at the bottom right of the board.
Steve w (2 years ago)
+Michel van Biezen I was just wondering if it made a difference in finding the derivative, I keep getting mixed up on the process steps, not really worried about the final answer and the algebra to follow, just about getting there
Michel van Biezen (2 years ago)
At this point, it simply becomes a matter of what form you want to leave the final answer as. I doesn't make any difference.
