Cos n pi 2 is a trigonometric function that represents the x coordinate of a point on the unit circle The value of cos n pi 2 for a given value of n can be found by finding the x coordinate of the point on the unit circle that is n 2 radians or n 90 degrees counterclockwise from the point 1 0 You can think of the positive exponential term as rotating counterclockwise and the negative exponential term rotating clockwise Since both exponential terms are of equal value i e 1 but only moving in opposite directions they cancel out at all points n cos x frac exp ix exp ix 2 the physical intuition follows from above

We write down the first four partial sums of cos n pi 2 in order to detect a pattern After writing down these first four terms it is clear that the series diverges when we check the The term is cos pi n 2 with n 1 2 3 4 5 I remember that you can convert these things into power series because they usually alternate between 0 1 or 1 In this case this one goes 0 1 0 1 0
