Use Integration by Parts to find frin :In(x)dx Sketch the graph of y=x+41. Using integration, find the area of the region bounded by the curve y=x+4| and x=-6 and x=0. Draw a rough sketch of the curve y =(x - 1) in the interval [1, 5]. Find the area under the curve and between the lines x= 1 and x = 5.
