Hello, I am doing this coursework and I am a little bit unsure about how to state my error for decimal search. I have established that the root lies between -2.28682 and -2.28683. Do I say that the solution is -2.2868 +/- 0.00005, since that was the root from my previous search that I have now established it is closer to? Or can I say that it is -0.286825 +/- 0.000005, as this will cover all values in my range? Thanks in advance for any help, BF.
