Let . Find potential function for . We know , so Differentiating wrt , . So we have + constant. The answers then simply state that the constant is just zero, not quite sure how they get to this? Thanks in advance

Therefore you can take any value you like for the constant. For simplicity they may have taken it to by equal to zero.
Ahh thankyou. I was debating whether you could basically choose your value of the constant. Cheers for the quick reply.
That g(x) should be g(y).

Thanks in advance You set your Then you have I have a different solution for your g(y) solution then what you obtained. I don't think you should have a 2/3 just a 1/3.
Thanks for the last two posts. You're both right, typos due to typing far too quickly lol. Cheers for spotting those
