I have to examine whether this sequence
Xn = ln(n^2+1) - ln(n)
converges or diverges.
My attempt at a solution:
Xn = ln(n^2+1) - ln(n) = ln((n^2+1)/n) = ln(n+1/n)
Xn → ∞ when n → ∞
So the sequence diverges.
Can someone look at this and see whether the procedure...
Hi
I'm trying to figure out whether this expression √(a^2+2ab-2ac+b^2+2bc+c^2) can be complex or not while a>0, b>0 and c>0.
My answer would be no but I'm not sure.
The explanation was good. Thank you.
I have one question concerning the parametrization of S.
since z=h(x,y) wouldn't a possible parametrization of S be :
r(u,v) = (v(6-u^2), u, 6-(6-u^2)*v-u^2)
?
I don't understand why you choose the boundaries for v to be that.
And the last two lines...wasn't x = v(6-u^2) with the boundaries -√6 ≤ u ≤ √6.
I'm a bit confused now :(
