Finding Stationary Points (Part 1) : ExamSolutions

[mostinho9]

you are awesome.

[aftab7471]

i asked my teacher that why we have dy/dx =0 for stationary points, so he gave me answer that it is a logic but he does not make any sense to me, when i said sir we can say it is zero because its gradient is zero , so he answered me that no that no the reason ,so i m confused hope u can make any sense to me:)

I learnt this last year, but was told I'd need to revise it for an upcoming exam, and your explanation was so concise and made it easy for me to recall the process! Thank you so much!!

@oHaRDz Hope your exam goes or went well.

[elliebarker1]

how would you solve dy/dx=42/2x^1/2-5/2x^3/2 to find a maximum point?

[hfdpayner]

Thank you so much

[ExamSolutions]

where the 3 went in the 2nd to last line minute 5:16

[ExamSolutions]

@3569159 3 as a factor cannot equal zero. You could look at it another way. divide both sides by 3.

You should also note that if your given a sketch of a curve, what seem to be points of inflection may not be..

The gradient doesnt allways equal 0 at places that look to be points of inflection.

Great vid!
