Hello, I really trying to understand what is going on with these summations.
the code is following:
for p = 2 to n
for i = 1 to n - p + 1
j = i + p -1
for k = i to j - 1
O(1) + O(1)
Does j enter anywhere here besides the upper bound of the inner-most...
Rules of Summation...Help Me Please
I have a vauge idea of what these rules mean:
1. \sum^n_{i=1}c=cn
2. \sum^n_{i=1}i=\frac{n(n+1)}_{2}
3. \sum^n_{i=1}i^2=\frac{n(n+1)(2n+1)}_{6}
4. \sum^n_{i=1}i^3=\frac{n^2(n+1)^2}_4
are these rules saying that if i have...
Good evening. I'm having a little difficulty with the summation of rectangular areas when finding the area under a curve.
Question:
Using summation of rectangles, find the area enclosed between the curve y = x^2 + 2x and the x-axis from x=0 to x=3.
Well, I start by dividing the interval...
I've heard something about Poisson summation in relation to Fourier analysis, but I can't seem to find any good info on the subject... Can anyone explain what "Poisson summation" is?
Furthermore, I would like to know exactly what "Parsevals identity" states and how it is applied.
Thanks.
Hi, I don't understand this problem at all:
Rewrite the following sum with the index of summation starting at 3 in summation notation:
\sum_{i=1}^{6}(5+3i)
I know that the sum is 93 but I'm not sure what to do...
Thanks for the help!
Is this simplified?
Use the power rule and the summation rule to find f ' (x) and simplify where possible
f(x) = ((2x^3)/5) - x^2 +3/8
f ' (x) = d/dt(((2x^3)/5) - x^2 +3/8) = ((6x^2)/5) - 2x
Is this the right answer?
How would I solve E1jk without the summation? I know how to solve it using the summation symbol but don't know howto do it without it.
Also, I need help proving that |torque|^2 = |r x F|^2= r^2F^2sin@(thetarF ). r dot F = rF cos (thetarF . Would I have to use (r x F) dot (r x F)?
