answer all parts please except A if you cannot
IF YOU HAVE ANY DOUBTS COMMENT BELOW I WILL BE TTHERE TO HELP YOU..ALL THE BEST.
ANSWER;
b.)
Now, the three paths can be parameterised as follows:
The paths are plotted below, where the black path is C1, the red one is C2 and the cyan path is C3, with the directions indicated:
Now, in the first case:
And, in the second case :
In the third case, by the theorem we have mentioned the two paths exactly cancel each other out, and thus we hence have
c.)
We see that the integral is independent of the path taken, and always equals zero. This is due to the fact that
, which implies that the line integral is path-independent.
I HOPE YOU UNDERSTAND..
PLS RATE THUMBS UP..ITS HELPS ME ALOT..
THANK YOU...!!
answer all parts please except A if you cannot (6) Consider the vector field F(x,y)-《22, 3y). A path is closed if it ends whiere it starts Consider the 3 closed paths starting and ending at (3,0): C...
please answer asap (it is all the professor asked) (5) Consider the gradient vector field F ▽f where f(x,y) = cos(2x-3y). Find curves G and C2 that are not closed such that JG F·dr = 0 and 1, F . dr-1. Explain why you pick the curve you do, and how you know the integrals have the correct values. (Hint: Try picking a straight line between the origin and some simple point (a, b) that you choose later.) (5) Consider...
Questions. Please show all work. 1. Consider the vector field F(x, y, z) (-y, x-z, 3x + z)and the surface S, which is the part of the sphere x2 + y2 + z2 = 25 above the plane z = 3. Let C be the boundary of S with counterclockwise orientation when looking down from the z-axis. Verify Stokes' Theorem as follows. (a) (i) Sketch the surface S and the curve C. Indicate the orientation of C (ii) Use the...
