Do you know how to take derivatives? And what happened to the absolute value brackets?....Errors are never negative.Also if you have a cos/sin function in an equation(multiplying) how would you do it for cos/sin?
is it just for cos x = sinxdx/cosx and cosxdx/sinx for sin x?
No, you would compute the absolute value of the partial derivative of [itex](R^2+z^2)^{3/2}[/itex] with respect to R and multiply it by the uncertainty in R; then do the same with respect to z, and then add them together...So would I just take the uncertainty on z^2 + R^2, then multiply in by 3/2 and squareroot z^2 + R^2?
