For R

##### Section 3: This problem requires finding the point of intersection of two functions. Using the function ```y = cos(x / 2) * sin(x / 2)```, find where the curved line ```y = -(x/2)^3``` intersects it within the range of values used in part (2) (i.e. 4001 equally-spaced values from -2 to 2). Plot both functions on the same display, and show the point of intersection. Present the coordinates of this point as text in the display.
