# Can someone help out?

I tried to invoke Green's theorem but couldn't as Green's theorem is valid for 2D vector fields and here I have a 3D vector field.

Can someone help ?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

by stokes theorem you would be able to convert this line integral into surface integral by the means of taking curl of line integral ie curl= cross product of vectors

Use Calvin Stokes Theorem maybe?

@Jake Lai , any ideas?

Stokes is for Surface integrals while here I have a line.

use stokes theorem for converting line to surface integral

Can you do it and show ? I tried.

is there any relation between x,yand z are given like in some parametric form or any boundary condition

@aryan goyat Bhaiya , I want to improve my physics. Please tell how to do it. Anything regarding books , problem books , websites , videos , contest problems etc. I want to clear NSEP this year and may it to OCSC atleast.

i think there is no place better than brilliant to improve your physics ,you can try mechanics problems by Deepanshu Gupta,Mvs Saketh,Ronak Agarwal as no can teach physics better than questions. i would also suggest you to complete irodov before NSEP , it will definately help and the next thing out in physics is to never give up in any kind of question , the more you think about it more good you become.I myself has now decided that i will weekly post one question with the title "Physics is Cool" and would try to post question from every topic ,each question carrying a new concept.

Thanks, Any theory book would definitely help.

though i don prefer reading physics but still i have seen people admiring hcv ,resnik and haliday,physics galaxy.
