A 2-dimensional potential flow is produced by three identical sources, each of strength Q. The sources are located at (x,y) = (-1,0), (0,1), and (0,-1).
a) Find a formula for the speed distribution on the x-axis for x >= 0. Make an accurate plot of this speed distribution.
b) Find the coordinates of all stagnation points in the (x,y) plane. Your answer must be accurate to at least three significant figures.
