I was asked this on exam today:
f(1,2)=8, f(1.01,2)=8.4, f(1,2.01)=7.8, f(1.01,2.01)=8.3 x=1±0.02, y=2±0.03
What is the limit of error in f?
I believe it should be the error propagation formula so I should use the data to approixate the derivate. Correct? But how do I approximate the derivates and is that the right way to go?
