Hello students, to find the call of vector field f, we can compute the call as follows.
00:07
So here f is given as 3z plus 3x square i plus 2y plus 7z plus 7 sin y square into j.
00:30
So call f equal to del fj by del y minus del fy by del z into i plus del fx by del z minus del fz by del x into j del fy by del x minus del fx by del y into k.
00:50
Let's calculate each component that is del fz by del y equal to 2.
00:57
Del fy by del z equal to 3, 7, 7.
01:05
So we found this one and this one, 2 minus 7.
01:12
Now del fx by del z equal to 3.
01:22
Del fz by del x equal to 0.
01:26
Similarly, we will get del fy by del x equal to 0 and del fx by del y equal to 0.
01:36
So call f equal to 7 minus 7, 0 i cap plus 0 j cap plus 0 k cap.
01:45
So it's 0.
01:49
Now the call vector field f is 0 since call represents the circulation of vector field.
01:56
It tells us the vector field has a 0 circulation around certain closed loops in xy plane.
02:04
So we can write for the b as call is 0 i plus 0 j plus 0 k...
