Differentiation (Maxima and Minima)

In this video I explain how to find stationary points and determine their nature. This video is intended for those studying AQA's Level 2 Further Maths GCSE.

Stationary points came up today as a 5 marker. We didn't go over stationary points in any detail in school, but thanks to your videos on differentiation, i was able to do the question incredibly easily. Thank you again for these great videos!

I jus wanna thank you brother u have jus explained me the entire concept in 8 mins where my teacher takes 40 mins
U are very efficient 😢❤❤

dy/dx of negative power gives negative power since you subtract 1 to the power and multiply base by the original power e.g x^-1: drop -1 to have -1x and subtract 1 from -1 to get power -2 combining the two the full derivative is -1x^-2 giving you -1 multiplying x^-2 or -1/x^2. I used power rule and laws of indices to write negative power x^-2 to positive power x^2

Great explanation but i have a question,
What if there are more than 2 stationary points, suppose i have to find maxima and i get three values of x for which first derivative is equal to zero,
and for two values of x, second derivative is negative.
Then how do i find on which value of x would there be maxima?
Do i have to put both of these value in original function to check which one gives greater value, or is there any other way to know?

Thank you so much 😊it made my topic crystal clear✨

[mahdi-hasan]

Thank you. It clearly explains the whole concept.

6:38 can you tell me how you got -1/x^2 when differentiating x^-1 plz

[ferrariamarela]

What if the second derivative is equal 0? is it a maxima or minima?

[moniquegeorge]

my factoring skills are trash, I'm mixing up the signs a lot
