|compare to this:
waaaait a minute, you basically divide the fourth line by (4x-3y), but what if 4x=3y (and judging by the first line it is
)? it brings us to 0, and you cannot divide by zero
also, integral, well, i thought (int)1/x(dx)=ln(x). don't know if you can have 1 there, that's a const, it should be outside of it.
