A curve C is called a flow line of a vector field F if F is atangent vector to C at each
Chapter 15, Problem 47(choose chapter or problem)
A curve \(C\) is called a flow line of a vector field \(F\) if \(F\) is a tangent vector to \(C\) at each point along \(C\) (see the accompanying figure).
(a) Let \(C\) be a flow line for \(F(x, y) = −yi + x j\), and let \((x, y)\) be a point on \(C\) for which. Show that the flow lines satisfy the differential equation
\(\frac{d y}{d x}=-\frac{x}{y}\)
(b) Solve the differential equation in part (a) by separation of variables, and show that the flow lines are concentric circles centered at the origin.
