8 AREAS BETWEEN CURVES Area between two curves

9 AREAS BETWEEN CURVES Area between two curves Find the area of the region bounded by the curves and Example: Both right-hand and left- hand boundary are lines Note:

10 AREAS BETWEEN CURVES Area between two curves Both right-hand and left- hand boundary reduce to a point Note:

11 AREAS BETWEEN CURVES Area between two curves The value of a and b (not given) Note: Steps: 1) Find the intersection points 2) Write the area as an integral

12 AREAS BETWEEN CURVES Area between two curves

13 THE SUBSTITUTION RULE T-092

14 THE SUBSTITUTION RULE T-102

15 AREAS BETWEEN CURVES

16 Area between two curves Some regions are best treated by regarding x as a function of y.

17 AREAS BETWEEN CURVES Area between two curves Some regions are best treated by regarding x as a function of y.

18 AREAS BETWEEN CURVES Steps: 1) Rewrite the function as x in terms of y 2) Find the intersection points

19 AREAS BETWEEN CURVES We could have found the area in by integrating with respect to x instead of y, but the calculation is much more involved.

20 AREAS BETWEEN CURVES T-092

21 AREAS BETWEEN CURVES
