Thread: Summations

Find the sum when n=1000. Show all your steps. Use the properties of summation.

i=1 -->n ((4i/n^2)+(i^3/n))*(6/i)

Thank you very much....I hope I hear back asap!!!

You're performing this sum, then?



If so, I would note two things:

1. You can simplify a bit before summing.
2. It's true from principles of induction that



So what does that tell you?

Thank you so much...you saved me!!!!

You're welcome. You have solved it, then?
