# Are the following equations inversely or directly proportional to frequency?

## Homework Statement

Re-arrange the eqation Fc=4π²mrf² to solve for frequency (f). State the relationship between frequency and (radius, mass, Fc).

Fc=4π²mrf²

## The Attempt at a Solution

Fc=4π²mrf²
$\frac{Fc}{4π²mr}$ = f²
$\sqrt{\frac{Fc}{4π²mr}}$ = f

I have re-arranged the equation though now I need to know the relation between:
•frequency vs mass (m)
•frequency vs Fc (Fc)

Which one is proportional and which ones are inversely proportional? (does the square root affect them)?

Just forget that there was a square root sign. You'd have Fc / 4n^2 * m * r.
The Square root does reduce the value of the expression inside, but does nothing to the relationships that you are looking for
