anonymous 4 years ago make L the subject Z=√R^2+(2πFL-1/2πFC)^2

1. sasogeek

if i'm reading this right, tell me if this is the equation $\huge z=\sqrt{R^2}+(\large \frac{2\pi FL-1}{2\pi FC}\huge )$ is this it?

2. sasogeek

and the bracket is raised to the power 2...

the best way to think of this is to make L stand alone, do whatever it takes :D ;) i believe the steps shown are self explanatory, if u still have issues, let us know :)

I am sorry angela210793

11. sasogeek

well in this case you'll have |dw:1330598202561:dw| just square both sides to clear the square root then solve from there :)
