In this question, the vector field f of x, y equals to y e to the power x y minus 1 i and plus x e to the power x y j is given.
00:16
Now, f is conservative, f is conservative if curl of vector field f is 0.
00:28
So, this implies curl of f that will be curl of f will be i j k.
00:38
Now, del by del x del by del y and del by del z coefficient of i is y e to the power x y.
00:49
So, y into e to the power x y minus 1 and coefficient of j that will be x into e to the power x y coefficient of k is 0.
01:02
Now, finding the determinant.
01:04
So, this is a plus, this is a minus, this is a plus.
01:07
So, this will be equals to i leaving this column this row.
01:12
So, del by del y of 0 minus del by del z of x into e to the power x y and minus j leaving this column this row.
01:26
So, del by del x of 0 minus del by del z of y e to the power x y minus 1 and plus k and leaving this row and leaving this row and this this column and this row.
01:44
So, this will be del by del x of...
