1. The problem statement, all variables and given/known data Evaluate ∫C F⋅dr along the line segment C from P to Q F(x,y) = 8 i + 8 j ; P (-4,4) , Q (-4,5) 2. Relevant equations 3. The attempt at a solution I believe I got most of the work done but I am have trouble finding the limits of the curve. What I have done was create a vector v=PQ= <0,1>. I then made the parametric equations: x = -4 y= 4 + t I then derived x & y to get a dr(t) = dt j F dot dr gives me 8dt..... combining everything I get ∫C 8dt. To find the limits of C I plugged Q into the parametric equations to give me values of t which were 0 & 1. Attached is my work to clarify, not sure if correct.
