like what would the next interval be after pi and -pi over 2??
phi
  • phi
cos is >=0 from -pi/2 to pi/2 so you can drop the | | for that inteval for pi/2 to pi cos is neg, so drop the | | and put in a -1 i.e. \[ \int_{\frac{\pi}{2}}^\pi - \cos x \ dx \]

|dw:1437337222962:dw| due to its symmetry, the interval in question is just 3, times the integral of cos(x) from 0 to pi/2
