## Homework Statement

Suppose the exact value of a particular definite integral is 6. The following questions refer to estimates of this integral using the left, trapezoid, and Simpson's rules. Use what you know about approximate errors to answer the following questions. Give your answer to 4 decimal places.

(a) Suppose Left(40)=2.3055. Estimate Left(120)

(b) Suppose Trap(40)=2.7250. Estimate Trap(120)

(c) Suppose Simp(40)=3.1680. Estimate Simp(120)

## The Attempt at a Solution

I know that Actual- Approximated= Error, but I am not sure how to use this concept

to solve the problem. I've tried to find the ratio of each, but not enough information

was given in order to estimate what it asked for. (In terms of "not enough information",

I mean--- Shouldn't they give us the actual function whose definite integral is 6?)

Please help me with the start and I'll try to figure out he rest!
