Exercise 3 Which of the following commands will plot a vector starting at P= (1, 3) and pointing to Q = (2,10)? quiver(1, 3, 2, 10) quiver(1, 2, 3, 10) quiver(1, 3, 1, 7) quiver(1, 1, 3, 7) Therefore what is the correct syntax to plot the vector from the point 11, y) = (X1,Y1) to (12, y2) = (x2,Y2) where (Ar, Ay) = (12 - 11,42 - y) = (DX,DY)? quiver(X1,Y1, X2,72) quiver(x1, Y1, X2, Y2) quiver (X1,Y1, DX,DY) quiver(X1, Y2, DX, DY) Not only can quiver plot vectors, but it can take the coordinates in a matrix form. Consider the following snippet of matlab code. Show/hide Matlab code snippet 2 [px, py] meshgrid(linspace(-1,1,11)); B = px; C = px.^2; h = quiver (px, py, B, C); set(h, 'ShowArrowhead','off') axis tight Which matrix holds the x coordinates of the points at which the vectors are plotted? Which matrix holds the vertical components of the vectors that are plotted
