I think I've solved it.
Someone please check my reasoning and my work.
We are given: . . The resonant frequency of an oscillation in electrical circuits
. . is given by the formula: .
If the error in measuring is 4%, and that measuring is 2%,
. . calculate the maximum percentage error in calculating ?
We have: .
Take differentials: .
. . Hence: .
Substitute : .
Therefore, the maximum percentage error in calculating is
