I l A Geometric Interpretation If the values of I are positive, tP.eequation d J X dx I(t) dt = I(x) a has a nice geometric interpretation: The integral of/from a.to x is the area A(x) of the region between the graph of I and the x-axis from a to x . Imagine the area swept out by a wiper blade clearing the .raindrops from the win"shield on a bus. .As the blade moves past x, the rate at which the cleared area is being swept out is precisely
