If the area for a circle is
, you can write it in terms of its diameter like this:
They are called identities because:
w-x = 0
w = x (carry x to the other side) is the same as x = w
in the other case:
wx-x = w / divide by w on both side
x -x = 0
x = x (carry x to the other side)
In both cases the equations are the same.
