Answer 1

giv it

Answer 2

this is the questopm

Answer 3

my solution.

Answer 4

what to do next? how to convert it into the required form of c? rather to what "thing" i equate it to?

Answer 5

write the parameters as at^b , t
cxydx + x^6y^2dy

Answer 6

theres a dt missing in ur equations

Answer 7

check my solution first. i have folllowed the steps.

Answer 8

i guess ur second line is ur final answer??

Answer 9

oh thats kinda rough work. well the final answer i m getting is on the next page (i ve posted two sheets)

Answer 10

u integrate it from t=0 to t=1

Answer 11

yea/

Answer 12

so ur done..thats ur work done

Answer 13

lol!
but thats not the answer. read the question. we need it in c form.

Answer 14

Answer 21

work done is F.dr

Answer 22

so uve done it right

Answer 23

as far as i can see

Answer 24

yes.

Answer 25

uve done it like line integrals are don like f(r(t))(r'(t))dt bt even F(x)dx + F(y)dy is correct..infact its the same thing

Answer 26

i need a in terms of c and show tht the work done is INDEPENDENT of b

Answer 27

i got (a^3b + 3ac)/3(b+2)

Answer 28

b is not in exponent

Answer 29

have they mentioned the value fr wrk done??i guess not

Answer 30

a=(3c/2)^.5

Answer 31

what i am doing is putting the work done = 0 and then calculating a.

Answer 32

and its not useful...

Answer 33

:-/

Answer 34

what do u say anwara?

Answer 35

Not sure, working on it.

Answer 36

Part of the question is missing, right?

Answer 38

na. nothing is missing.

Answer 39

come on people. some please solve this question!

Answer 40

The question is not even saying what it wants. I don't know why it's solving for C, that's why I asked if something is messing. For the Work, I got the same answer as yours, him got the same answer too.

Answer 41

It's making me sick, the last thing that the question says is that a>0 and b>0. It's not telling what I am asked to do. If you could check the question again, that would be good :)

Answer 42

i have taken the picture of the question and pasted it.

Answer 43
