Subtracts the value of the cell in Row
1,
Column
4
from the value of the cell in Column
3
of the cur-
rent row.
Multiplies
2
cells in the same row.
Divides the value
of
the cell in Row
1,
Column
2
by
100.
Calculates the cube of the value of the cell in Row
3,
Column
6.
Multiplies the value of the cell in Row
2,
Column
3
by
-1
if (and only if) it is
a
negative number
(absolute value).
Displays the arctangent of the value of cell
R3C5-the angle that has its tangent equal to the
value of cell R3C5. (The result displays in radians;
use
ATN(R3C5)*57.29578
to display the arctangent
in degrees.)
Adds all the values in the current row, beginning
with Column 1, over to the current cell, skipping any
non-numeric data, and divides by the number of
numeric cells added.
Gives a cumulative total for Column
3,
beginning
with Row
4.

are selected and the
above formula is entered, calculation produces the

Displays the cosine of the value of cell R3C5. (Use
COS((R3C5)*.01745329)
if the value in cell R3C5
is
in degrees instead of radians.)
