SUMMARY
The forum discussion centers on the variable change in definite integration as presented in "Physics for Scientists and Engineers" by Randall D. Knight. The user inquires about the substitution of variable r with variable u, defined as u = z² + r². The derivative of u with respect to r is established as du/dr = 2r, with z treated as a constant. The user confirms their understanding of the concept after receiving clarification.
