10. By filling in the following blanks and table, estimate the area under the curve f (x) = 1 between r = 1 and x = 4 using n = 5 subintervals using a LHS, then again using a R.HS. Use all the notation above throughout your calculations and draw pictures illustrating your work. b = AT = 1st interval: : 2"d interval: 3"d interval: 4th interval: : 5th interval: a = = b Width LHS Ht RHS It LHS Arca RHS Area IIII LHS ~ RHS ~
