(D)  USE OF SPECIAL SCALES ON COMMON SLIDE RULES
========================================================================

CI & DI Scales
**************
These scales are reciprocal to the corresponding C & D ( = X ) scales:
CI = 1/C ;  DI = 1/D. They make an efficient way for (1) multiplication
and (2) are useful in replacing division by multiplication. This may be
also used to avoid re-setting of the slide,  when the next number to
proceed would be outside of the slide.

Example (1):   12.3 * 4.56  =  12.3 / ( 1 / 4.56 )  =  56.09
------------
Set 4.56 on CI scale opposit to 12.3 on D scale (»division« operation)
and read the result on D scale under the right »1«.
 
Example (2):   12.3 / ( 4.56 * 2.34 )  =  1.153
------------
Set 4.56 on the C scale opposite to 12.3 on the D scale. Move the
hairline to 2.34 on the CI scale (»multiplication« operation) and
read the result on the D scale.

CF & DF Scales
**************
These scales are »folded«: CF = π * C ;  DF = π * D.  They begin at π
and the »1« is nearly in the middle of the rule. Any setting of C or D
is automatically set on CF and DF too; therefore they can be used for:

(1) Multiplication and division in the same way as with C & D
(2) For all calculations involving multiplication (or division) of π
    eg.: Diameter * π = Circumference.
(3) Most important is the use of CF & DF to avoid re-setting the slide.
    If the next number to proceed would be outside of the slide,
    it can be made on the CF & DF scales!

Example (2):   3.45 * π = 10.84
------------
Set the hairline on 3.45 on D scale and read the result on DF scale.

Example (3):   1 kg = 2.2 lb    3.4 kg = ?    5.6 kg = ?
------------
Set the 2.2 on the C scale opposit to the left »1« on the D scale. 
For 3.4 on D scale the result 7.48 is on C scale - but for 5.6 there
is no C available: Read 5.6 on DF and the result 12.3 on CF scale.

CIF & DIF Scales
****************
These scales are reciprocal to the corresponding CF & DF scales:
CIF = 1/CF ;  DIF = 1/DF. Same is true, what is said above for CI & DI.


(E)  COMMON MARKS ON THE CURSOR
========================================================================
FAQ:
****
"Why my cursor has 3 vertical lines: A long black one in the middle, a
red one in the left upper half, and a red one in the right lower half?
- And I have seen other marks too..."

Answer:
*******
When the black hairline is set (on C or D = X) on the DIAMETER, than
the left red line shows (on B or A = X2) the AREA of the CIRCLE - or
when the black line is set (on A or B = X2) on the AREA of the CIRCLE,
than the DIAMETER can be read under the right red line (on D or C = X).

Common is the relation between the middle and the upper-right hairline
on the cursor for the  CONVERSION  1 [kW]  = 1.3596 [PS] on scales A/B.
Sometimes this relation is with the left to the right hairline on C/D.

MERCHAND SRs have often a shorter hairline left of the middle hairline
to calculate the INTEREST-YEAR with 365 DAYS ( instead of 360 days ).


(F)  MARKS ON SLIDE RULES AND THEIR MEANING
========================================================================

e  = 2.71828                  Euler's Constant = Base of Log.Naturalis
π  = 3.14159                  Circular Constant
c  = sqrt(4/π) = 1.128        for Area-to-Diameter Conversion
'  = π/4 = 0.7854             for Diameter-to-Area Conversion
ρ  = π/180 = 0.01745          Multiplier Degrees-to-Radians
R  = 180/π = 57.29            Multiplier Radians-to-Degrees
ρ' = 60 * 180/π = 3437.7      Multiplier Radians-to-Degrees in Minutes
ρ" = 3600 * 180/π = 206265    Multiplier Radians-to-Degrees in Seconds

1 kW = 1.3596 PS = 1.3410 HP  ;     1 PS = 0.7355 kW ;  1 HP = 0.7457 kW
