The Treehouse Attachment Bolt, Weekly Project 5

Continuing with my use of a Treehouse Attachment Bolt, I:
✅ define a vector field, v(x)
✅ find the divergence of v(x)
✅ verify LHS of Divergence Theorem by hand
This presentation satisfies weekly project #5 of @PurdueCE's Advanced Structural Mechanics (CE570).
