# Calculus 1- Question involving Riemann Sums

Use a calculator or computer to compute the left and right endpoint Riemann sums for the given function over the given interval with the specified number of equal intervals.

(a) f(x) = x+1, [−2,3], n = 25

This requires basic arithmetic. What is preventing you from doing the calculations?

right so I think I was able to do the calculations and got an answer of 140 to be on the left and 135 to be the right

140 and 135 are too high. Visit this graph to see if it helps you understand what is going on. The width of each rectangle is 1/5. For left hand endpoints you need to calculate f(left) for each rectangle and multiply by 1/5. desmos.com/calculator/y0j9hsbn73

ok so I am inputting Σ(2+i/5+1,i,1,25) like this for the right hand side into my calculator and from some reason I keep getting 140

First calculate ∆x which is b-a/n: (3-(-2))/25 = 1/5 Then calculate x_i which is 2 + i∆x: 2 + i * 1/5 = 2 + i/5

and these are the steps I took to find the right
