hey can ne1 explain how to find nature of stat. poitns..stuff like that..cos ireally don't get it...cos i was doing this uqestion right..and i found da second derivative equal to zero, doesn't that mean point of inflexion occurs... i dunno but tha answer said it was a minimum..please educate me
yeah i knoe thats da final asnwer, just wat did he do with the y and square root sign?? i'm guessing he elt it equal 2 zero and divded through by 2 and then square both sides?
hey umm bro, that question is wrong unless u skipped sum steps?? in ur firs tline of wroking.. tha question iz:
y=2"square root"(25-x^2)...state the domain and range
hey i'm haing trouble with this paper..duno what domain/range is and need help on folowin questions
5 a) and part b) also
6 c part iii
Thanx for da solutions in advanced
