Answer 1

Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

Answer 2

you can only approximate

Answer 3

or I think there is a limit

Answer 4

rearrange

cosx =xsinx
1/x = tan(x)

Answer 5

now

tan(x) -(1/x) =0

Answer 6

ahh I dont know what to do from now, best you can do is approximate

Answer 7

Thanks, this is the second derivative and I'm trying to find the inflection points. Wolframalpha gave me the answers, but not the steps needed.
