i have difficulties in solving the problem about stoke's theorem:
" Given u=(y+x2 ,3y,2xz)
surface: 1/4 of the circular cylinder 4=y2+x2 and z is on the interval I=[0,6]
verify the stoke's theorem over the region mentioned above."
Answer is -4(pi) but i could not find the answer.
i would be appreciated if anyone help me to solve this question.
