Question

Find the possible inflection points of the following equation

Answer 1

\[x \sqrt{5-x^2} \]

Answer 2

i guess this means you need the second derivative
did you find it?

Answer 3

Yea i need it and i started working it out in class but i stopped because it got really complicated and i thought i was doing it wrong.

Answer 4

did you get
\[f'(x)=\frac{-2x^2+5}{\sqrt{5-x^2}}\]?

Answer 5

I dont remember but for the second deriviative i think i got \[\frac{x(2x^2-15)}{ (5-x^2)^{3/2} }\]

Answer 6

@satellite73 you there?
