Hello, I have a bit of a head scratcher that I wonder if you could point me in the right direction. It's an assignment so I don't want the answer really, I just want to know the way I do it and as long as I understand that I can get the rest. basically I have a data set v/mV C/Mbyte 0.1 40165.0678 0.2 3127.0092 0.3 695.9694 0.4 186.1705 0.5 63.6404 20 15.7080 40 132.1926 60 704.3505 80 6447.1927 100 53815.9419 now I have a bunch of questions on this that end up with suggesting an equation which is C = Av^m + Bexp(Kv) now I know v and C but nothing else and it is baffling me. Anyone have any ideas? I have the questions on a document somewhere if this would help. Thanks
