The area under the curve from x = –4 to x = –2 is exactly the same as the area from x = 0 to x = 2. Hence the factor 2 in front of 7 – x2 dx. The area from x = –2 to x = 0 is the same as the area from x = 2 to x = 4. It would be wrong to find2x – 1 dx. 5) Let Pn be the statement: r2 = n(n + … ................
