I wish I could delete this thread because I just found out the unit is an Angstrom, 10^-10 meters

found it in windows character map Å

I'm sorry if this is the wrong forum but in a problem I was given wavelength with the unit as an A with a circle above it, can anyone tell me what this means and how I can get it into more familiar terms (meters, for example)?

Say something is a value +/- .05. What happens when you take the inverse of the value? For example, 30 V +/- .05 V. 1/V...what would the error be?

ahhhh...thank you. it's relatively early in the semester and i may have partied too hard over winter break ;)

Homework Statement This is to find the arc length of r= \theta from 0 < \theta < 2pi I ended up with \int\sqrt{\theta^2 + 1} Homework Equations \int\sqrt{\theta^2 + 1} The Attempt at a Solution I couldn't see a relevant way to do integration by parts so I went with trig...
