Here is a practical problem in mma. I often want to compare if two
equations are identical, how to do that?
For example, I want to know if eq1 and eq2 are the same equation. Testing
by numerical methods, or by graphical look-and-see are ok, as long as
it's relatively easy and correct. (i.e. I don't need a rigorous proof)
eq1 = 3/(-8) Log[1-4 y[x]^2/x] == Log[x] + c
eq2 = (x^2 - 4 y[x]^2)^3 x^2 == c
c is an arbitrary constant.
