The interval [0,4] is partitioned into n equal subintervals and ti, is chosen in [Xi-1, Xi] for each i.
x->inf......Ʃ e^(sqrt ti)/N(sqrt ti)
The Attempt at a Solution
It was problem we had to do in class as a group, teacher wasnt there to provide us an answer, and some people in my group have conflicting answers
What i did:
I wrote it as integral
∫ (e^(sqrt X))/(N(sqrt X))
I then use the substitution method:
U= sqrt X
du= 1/(2 sqrtX) dx
2du= 1/(sqrt X)
2/n ∫ e^u = (2e^(sqrt 4))-(2e/n^(sqrt 0))
My answer = 2/n(e^2 - 1)
Can someone help me out, i dont really understand what we are suppose to do, and i apologize for the bad input. Appreciate it.
