Use green's theorem to evaluate f · dr. c (check the orientation of the curve before applying the theorem.) f(x, y) = e^−x + y^2, e^−y + x^2 , c consists of the arc of the curve y = cos(x) from (− π/2 , 0) to (π/2 , 0) and the line segment from (π/ 2 , 0) to (− π/2 , 0)

step-by-step explanation:

where is the question is there is a formula or is there not one

this is a good question! i'll do some research and come back when i have the answer!

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
