Trying to figure out a problem in my textbook. In my exercise in a textbook, a problem says that Determine the error in the approximation given that the actual length is $3.7437137$.
And in the solution in the back of the book, it says that The approximation is $3.743713701$ with an absolute error of $0.2226462$
How is $|3.743713701-3.7437137|= 0.2226462$ ? I am confused. Any help is appreciated
There's a typo. The actual length is $3.96635989732264...$
