Hi, I've just come across a question in the June 2012 MEI NM paper (question 7) where you have to find 3 estimates for the root using the secant method. Should I be using the rounded value (usually 6 dp in the mark scheme), or the value saved in my calculator to work out the second and third estimates?
When I did the paper I used my calculator values, but the mark scheme has used rounded values... If this was being marked by an examiner, would I still get the marks?
Who do you think it is...
