Question

bit more help. thanks

Answer 1

f(x,y) is the potential function, work done equals difference between `final and initial` values of potential

Answer 2

for c : P to T to Q

final = Q
initial = P

work done = `value of f(x,y) at Q` - `value of f(x,y) at P`

Answer 3

12-5 for part b. part a is shorter than.

Answer 4

i think u can simplify 12-5

Answer 5

well, yeah.

Answer 6

just in my notes putting that so i know where it came from. lol.

Answer 7

Okay :)

Answer 8

so for part c is it still 12-5? start minus end? discounting the point in between? or does that matter?

Answer 9

the path doesnt matter for gradient fields

Answer 10

work done = final value - start value

Answer 11

so part b and c are same : 12-5

Answer 12

ok, and the last one is 0 cause it starts and stops in the same place.

Answer 13

Yep!

Answer 14

i thought part d would be 12-5 then (s-p), but it's not....

Answer 15

S --> P

final = P
start = S

Answer 16

it would be `5-12` for part d

Answer 17

oh. backwards. lol. got it. very tired.

Answer 18

thanks

Answer 19

its called fundamental theorem of line integrals, look it up in ur notes when free :)

Answer 20

yeah, i have a notetaker for my ADHD so i can focus on paying attention and she hasn't posted yet.
