look for some proof for the formula of the divergence operator in cylindrical & spherical coordinate
is there any on the net ?
TNX !
the formula here:
http://hyperphysics.phy-astr.gsu.edu/hbase/diverg.html
cotan(t) = cos(t)/sit(t)
the limits of integration on u & v simply received from the projection of the region bounded by V on the UV plane -> you can see it circle with radius R=1 .
the limits of integration on z:
you can see in sketch : 0<=z<=U+V (of course just for u & v that in...
hello !
need to find the volume of V: { x^2+y^2=z , x^4+y^4=1 }
i dont know how to set up the triple integral caue i didnt find any way to understand the surface projection on the xy plane .
I would appreciate any help ....
need to calculate the limit of the series
(cos(a/n))^(n^3) n goes to infinity and a=!0
i try that :
e^L
L= the limit of (n^3)*ln(cos(a/n))
what now ???
TNX !
hello HallsofIvy ! , " I assume you mean prove that f is bounded in [a, infinity)."
that is right , i dont understand why did u choose epsilon=1 is it necessary ?
TNX!!
need to prove that f(x) bounded if f(x) continuous in [a,+infinite] and if theres a limit while x goes to +infinite.
I would really appreciate any kind of help !
need to prove theres limit by cauchy criterion
http://mathworld.wolfram.com/CauchyCriterion.html
the sequence: {X_n}=(10/1)(11/3).....(n+9/2n-1)
my try :
is that right ?
