Net area from graphs The accompanying figure shows four regions bounded by the graph of y = x sin x: R1, R2, R3, and R4, whose areas are 1, π − 1, π + 1, and 2π − 1, respectively. (We verify these results later in the text.) Use this information to evaluate the following integrals.

- By expanding (xh)2+(yk)2=r2, we obtain x22hx+h22ky+k2r2=0. When we compare this result to the form x2+y2+Dx+Ey+F=0, we see that D=2h,E=2k, and F=h2+k2r2. Therefore, the center and the length of a radius of a circle can be found by using h=D2,k=E2 and r=h2+k2F. Use these relationship to find the center and the length of the radius of each of the following circles. x2+y2+4x14y+49=0arrow_forward3 Find the area between y = 2x and y = 2x° from x = 0 to x = The area is (Simplify your answer.)arrow_forwardEvaluate the ff.
