Answer

From the graph, we find that the two curves intersect at approximately x=1.114 and x=2.03 within the given interval

Steps

Step 1 :First, get rid of the fraction by multiplying both sides of the equation by x: 1=xsin(x)

Step 2 :Then, to isolate x, set the equation equal to zero: xsin(x)1=0

Step 3 :This equation cannot be solved algebraically. So we use a graphing calculator or software to find the intersections of y=xsin(x) and y=1 over the interval [0,2π]

Step 4 :From the graph, we find that the two curves intersect at approximately x=1.114 and x=2.03 within the given interval
