given the force vector field F = <y,a> .
Find the work in moving an object through the vector field along the closed curve C formed by the arc of the ellipse x=acost , y=bsint, lying in the first quadrant, the x-axis, and the y-axis.
Please help me. thank you very much.
i've seen that notation before. it is from vector calculus, and you see it even in calc 3. in general we can use to represent a vector with components. if the components are functions, as opposed to just numbers, we obtain a vector field, that is, a function that assigns an nth dimensional vector to each point
