-π/2 < arctan(x) < π/2
So cos(π/2) < cos(arctan(x)) < cos(0)
0 < cos(arctan(x)) < 1
Sample Response: The base area , radius, and diameter can be
determined when given the volume and height of a cone. Substitute the
values for the corresponding variables into the formula, and then solve
by simplifying and undoing operations to isolate the variable. To find
the diameter, double the radius.
