Answer #1

1) Set a range with resolution .001 in order to match the required accuracy.

2) Calculate the left hand side and the right hand side.

3) Calculate the error and get it's absolute.

4) Divide the absolute value of the error by ex to get the percent error.

5) Checking if the percent error exceeds the limit or not.
