Area Between Two Curves

7.1

• If f and g are continuous functions on the interval [a, b], and if f(x) > g(x) for all x in [a, b], then the area of the region bounded above by y = f(x), below by y = g(x), on the left by x = a and on the right by x = b is….

• Find the area of the region bounded above by y = x + 6 and below by y = x², and bounded on the sides by the lines x = 0 and x = 2.

• Find the area of the region bounded above by y = x + 6 and below by y = x², and bounded on the sides by the lines x = 0 and x = 2.

• Find the area of the region that is enclosed between the curves y = x² and y = x + 6

• Find the area of the region that is enclosed between the curves y = x² and y = x + 6

• Find the area enclosed by the curves

and

• Find the area enclosed by the curves

and

• Sketch the region enclosed by and then find the area.

• Sketch the region enclosed by and then find the area.

• Find the area of the region that is enclosed between the curves x = y² and y = x – 2

• Find the area of the region that is enclosed between the curves x = y² and y = x – 2

#1

• Subdivide the regions

• Equation of top graph – equation of bottom graph

• Equations must be solved in terms of y and bound are determined by x values

• Reverse the roles of x and y

• When reversing roles you always subtract the graph on the right – graph on left

• Must solve equations in terms of x and gets bounds in terms of y

• Find the area of the region enclosed by the curves and x = 1.

• Find the area of the region enclosed by the curves and
