Inequalities? :3 Is there a way you can do it without that? /me never learned about inequalities
@mahmit2012 Alright. :/
@mahmit2012 is giving you a good method
Critical points?:3
@mahmit2012 How would I find those points?
You should find the critical points with Matlab or other software .
Alright. And that will show me the ranges? :) Thanks!
