A particle moving in a sheet where -1<y<1 and 0<x<5. It will start at x=0 and between -0.5<y<0.5. After each step, it will move a distance defined by d=0.2*log(rand()) and a random angle from –pi/4 to pi/4. Plot a sample movement. Find after 1000 iterations how many particles make it to the end of the sheet (ie. X>5).
