y = 0.125x8x, which is shaded below. 10 T I 10 1 T 15 Let R be the region bounded by the graphs of y = 10 sin (x) and 1 25 a) Find the area of R. If you use a graphing calculator or DESMOS, then be sure to write (using proper notation) the definite integral you are evaluating. b) The line y = -13 splits the region R into two regions. Find the area of R that is below the line y = -13. You will need to use Desmos or a graphing calculator to find the points of intersections between y = -13 and the given graphs.
