Best ResponseYou've already chosen the best response.0but how do i use it in this problem?

Best ResponseYou've already chosen the best response.0the derivatives is a function that describe the slope in every part of your main function, also in the 3 point ;)

Best ResponseYou've already chosen the best response.0I wrote it, df/dt is the derivatives of f(t) in t variables, maybe you like more f'(t)=8t2/t^2 ?

Best ResponseYou've already chosen the best response.0I know you gave 8(3) 2/3^2 then 242/9

Best ResponseYou've already chosen the best response.0ehm, sum XD I was lazy to sum the numbers, 218/9 is your slope

Best ResponseYou've already chosen the best response.0i Dont know if that's right bcause when I plug that in to the system im on it's saying its wrong

Best ResponseYou've already chosen the best response.0douch! maybe I've failed the derivatives!

anonymous

Best ResponseYou've already chosen the best response.0yup I failed, currect derivatives is: f'(t)=8t8/t^3 sorry man

Best ResponseYou've already chosen the best response.0hold on but the eqaution is f(t)=4 t^2 + 4/t^2.
