Rank Correlation Coefficient

Also identified as the spearman rank correlation coefficient, its reasons is to establish whether there is any form of association among two variables where the variables arranged in a ranked form.

R = 1 - {(6∑d2)/(n(n2 -1))}

Whereas d = difference among the pairs of ranked values.

n = numbers of pairs of rankings.

Let u = sin(x). Then du = cos(x) dx. So you can now antidifferentiate e^u du. This is e^u + C = e^sin(x) + C.  Then substitute your range 0 to pi. e^sin (pi)-e^sin(0) =0-0 =0
