**Reimann's Law..maajoor Helpp!**

**1. Use Riemann sum ( do NOT use fundamental theorum of Calculus) to calculate**

(integral) b= 1 and a =0 e^x dx

(integral) b= 1 and a =0 e^x dx

Attempt:

(delta x)=b-a/n 1-0/n =1/n

xi = 1/n

(integral) b=1 a=0 sigmaf(xi)deltax

limn->infin sigma f(i/n)1/n

use eqn to get...limn->infin 1/nsigma{e^(i/n)}

limn->infin 1/n e^1/ni

limn->infi 1/ne^1/n n(n+1)/2

limn->infin 1/n e^1/2(n+1)

then sub for n (table n | Rn where n =40,100,500,1000,5000 and Rn should be close to 1.72(got that using FTC2)...so the eqn must be wrong :D

**3.**
