Finding a parametric form and calculating line integrals.

Click For Summary
SUMMARY

The discussion focuses on finding a parametric form for the line segment C from the point (1, 0, 0) to the point (0, 2, 1) and calculating line integrals for the vector field v = xi - yk. The parametric representation of C is given as (1-t)i + (2t)j - tk, where t ranges from 0 to 1. The line integrals ∫C V·dr and ∫C v x dr are to be computed, with the vector differential dr needing to be determined based on the parametric form.

Homework Statement


Let C be the straight line from the point r =^i to the point r = 2j - k
Find a parametric form for C. And calculate the line integrals ∫cV*dr and ∫c*v x dr where v = xi-yk. and is a vector field

Homework Equations

The Attempt at a Solution


For parametric form (1-t)i + (2*t)j - t k
For second part i need help

Hello Yogi, welcome (belated) to PF :smile: !

So you have ##\vec v = x \hat \imath - y \hat k## and need ##\vec {dr}##, right ?

The path is from (1,0,0) to (0,2,1) , starts at t = 0 and ends at t = 1 in the parametric form. What would be ##\vec {dr}## ?

When I think over what to do for this one, I make a little drawing and check
