EXAMPLE

Multiply 15,, 21' 40" by 3.

d.

To divide an angle by a given number, it is necessary to divide each

column by the number, beginning with the "degrees" column. The remainder in

degrees, if any, must be changed into minutes and added to the "minutes"

column.

The division is then performed on the "minutes" column.

The

remainder in minutes, if any, must be changed into seconds and added to the

"seconds" column.

Finally, the division is performed on the "seconds"

column.

EXAMPLE

Divide 71,, 22' 42" by 3.

Answer:

23,, 47' 34"

Trigonometric Tables

a.

In order to facilitate the solution of trigonometric

problems, tables have been prepared which give numerical values to the sine,

cosine, tangent, and cotangent of angles from 0,, to 90,,.

b.

(1) Tables 6 and 7, on the following pages, are an excerpt from the

trigonometric tables listed in Appendix C-4 of FM 43-3.

Notice that the

heading for degrees (that is, 43, 44, 45, and 46) appear both at the top and

at the bottom of each page.
