What you're saying makes sense...thanks!

Thanks for responding... Yes, I'm in college and I'm using excel...I have considered error propagation. The problem I'm having is that each volume measurement I have also has a random error from the measurement (0.02 ml in this case). When I calculated the "second derivative" (really I...

I have an error analysis question...I carried out a titration, and I have error for each measurement, but I then took the second derivative of the data and graphed it. The actual value I am reporting was estimated from the x-intercept of this graph. The curve was not fit to anything. How do I...

Thanks for responding! I considered that, but it doesn't seem correct to just throw out the complex part...is there something I'm missing?

I'm trying to calculate the structure factor for a polymer melt: S(q)=\sum_{k}\sum_{j}\epsilon^{i*<q>*<r_{kj}>}, but I don't know how to deal with the imaginary exponent...(the rest of the variable don't really matter, because I'm confused about how to deal with the exponent, but q is the...
