**Reiny**, Sunday, January 24, 2010 at 8:49amDid you make your diagram?

I read your question as estimating the definite integral of √(1+x^2) from 0 to 3

You should be looking at 3 trapezoids with a base width of 1 each and the heights for the values of x = 0,1,2,3 would be 1,√2,√5, and √10 respectively.

The estimated area would be

(1+√2)(1)/2 + (√2+√5)(1)/2 + (√5+√10)(1)/2

= (1/2)(1 + 2√2 + 2√5 + √10)

= 5.73

check my arithmetic.
