Evaluate the Line Integral $\int _ { C } y z d x + x z d y + x y d z$

Short Answer

Evaluate the line integral $\int _ { C } y z d x + x z d y + x y d z$ , where $C$ consists of line segments from $( 0,0,0 )$ to $( 2,0,0 )$ , from $( 2,0,0 )$ to $( 1,3 , - 1 )$ , and from $( 1,3 , - 1 )$ to $( 1,3,0 )$ .
