Calculator Assignments due in recitation
Make sketches of the calculator screen and hand those in when
called for. Be sure to indicate the axis scales on any sketch.

Sketch the region and find its area (if the area is finite)
a.) S = {(x,y)| 0 <= y <= 1/(x^2 - 2*x + 5)}
b.) S = {(x,y)| x >= 0, 0 <= y <= 1/sqrt(x+1)}
c.) S = {(x,y)| 0 <= x <= Pi, 0 <= y <= (tan(x)*sec(x))^2}
d.) S = {(x,y)| 3 < x < 7, 0 <= y <= 1/sqrt(x-3)}
