sorry i realise that is lnx^2=ln(t+1) correct or would i be best off moving x & (t+1) up to the top and have X^-2.dx=(t+1)^-1.dt and integrate from there?
This would give me X^-1/-1=(t+1) ?????
The integral of
is definitely NOT
, you should be able to see that by taking the derivative to check your work. The second version is correct, and again you can check by taking the derivative. And you have to integrate both sides, not just the one, remember, you have to do the same thing to both sides if you want things to balance, if you just integrate one side that's like adding 5 to just one side, you cannot expect things to be the same on both sides if you only do things to one of the sides. Also, don't forget your +C after integrating.
