2.15 : The Maclaurin series expansion for the cosine is cos x = 1 - x^2/2! + x^4/4! - x^6/6! + x^8/8! - ... Use Mathematica to create a plot of the sine (solid line) along with a plot of the series expansion (black dashed line) up to and including the term x^8/8!. Use the built -in function factorial in computing the series expansion. Make the range of the abscissa from x = 0 to 3Pi/2.
