## Homework Statement

Evaluate the path integral [tex]\int (x^2+y^2+z^2)dr[/tex] from a =(0,0,0) to b= (3,4,5).

## Homework Equations

## The Attempt at a Solution

I'm lost. Had the dr been a ds I could do it, but my calculus book only deals with situations where [tex]\int F.dr[/tex].Edit: I figured it out, it's been a while since I've had calc 3.

I had forgotten what r represented. r = xx^ + yy^ +zz^.

You then multiply dr by x^2 + y^2 + z^2 and go parametric.
