Are my answers to a and b correct?
a) In a three-dimensional situation, the spatial variation of a scalar field is given by the gradient. What is the one-dimensional counterpart? Answer:The derivative
b) In a three-dimensional situation, a volume integral of a divergence of a vector field can be transformed into a surface integral (Gauss’s theorem). What is the one-dimensional counterpart? answer: Integration by parts
I have searched for this question but I can't find the right answer to question c. Can anyone help me?
c) What is the one-dimensional counterpart to the Green-Gauss theorem?
