Which integral expression can be used to find the area in the first quadrant bounded below by the x-axis and above by the curves y = sin x and y = cos x?

Question

ranga · Answer

Draw a graph of sin(x) and cos(x) for x = 0 to pi/2  (first quadrant) so it will be easier to see the area bounded by the two curves and the x-axis.
Find the point of intersection.
Split the integral into two parts.  Integrate the proper curve from 0 to point of intersection and add to it by integrating the second curve from point of intersection to pi/2.

would it be integral of sinx+cosx from 0 to pi/2?
