Oh,thank you,I got it
Well, you can say thatand then substitute that into the second equation you are given. Then you can get y.
Well,even if i findi will need x and y so that they follow those 2 equation,what formula would be then?
Well,even if i findi will need x and y so that they follow those 2 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?
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.
