anonymous 4 years ago What do you make of this phrase? "If the density at any point in G varies as its distance from the xy-plane..."

1. anonymous

Can we say that the density is equal to the distance from the xy-plane?

2. anonymous

not equal...just proportional

3. anonymous

Say we denote density by $\delta$, and the distance from the xy-plane by d. How can we represent density in mathematical terms?
