Thread: Easy Equation, stuck on the constant.

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

Dear craig,

You have a arbitary constant. 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).

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
