Amachinist is required to manufacture a circular metal disk with area 1000 cm2.
(a) what radius produces such a disk?
(b) if the machinist is allowed an error tolerance of ± 5 cm2 in the area of the disk, how close to the ideal radius in part (a) must the machinist control the radius?
(c) in terms of the e, d definition of lim x? a f(x) = l, what is x? what is f(x)? what is a? what is l? what value of is given? what is the corresponding value of d?
