## Homework Statement

The rate at which the mass–spring system loses energy to its surroundings is referred

to as the Q-value for the oscillator. The Q-value is defined as:

Q=2π(E/ΔE)

I need to find ΔE/E, which is the fractional energy loss per cycle of the oscillation.

How would I rearrange this so that ΔE/E = 2π/Q

## Homework Equations

Q=2π(E/ΔE)

## The Attempt at a Solution

I've no idea how to rearrange it so that E/ΔE is swapped round
