Formula for equation
You were right about that integral(my brother didn't knnw the solution either,but now he has given me another problem-
make a formula using a and b for x and y.#2 2012-10-29 13:16:38

Re: Formula for equation
When the two sides are added together, the left hand side turns out to be (x-y)^3. From there you can get:
Can you continue from here?
The limit operator is just an excuse for doing something you know you can't.

Re: Formula for equation
Well,even if i find
i will need x and y so that they follow those 2 equation.#4 2012-10-29 13:38:40

Re: Formula for equation
Well, you can say that
and then substitute that into the second equation you are given. Then you can get y.The limit operator is just an excuse for doing something you know you can't.
