Title: Question about the posted solution for HW1 3c
Post by: Yuanhan (Phyllis) Peng on January 27, 2022, 12:39:22 PM
I am confused about why when we integrate the left hand side Ux/e^u, we used the x' in Ux(x', y) expression, but we didn't change x in e^u(x,y)

The screenshot is attached.

It was a misprint; it should be $e^{u(x',y)}$ in the denominator
