Operation Manual
• Enter a number and then press the softkey with the appropriate trigonometry math function.
(Press the
SHIFT softkey to switch between the upper and lower functions.)
For example, to enter a radius that has a value equal to the square root of 2, follow this
procedure:
Highlight the radius field.
Press the 2 key.
Press the CALC key.
Press the TRIG softkey.
Press the SQR ROOT softkey. A value of 1.4142 will appear.
Whenever you’re calculating the SIN, COS or TAN of
an angle, enter the angle first and then
press the appropriate softkey. If you were to enter a value
of 30 into a numeric field, then press the
SIN softkey, a
value of 0.5000 (the SIN of 30 degrees) would appear.
Continuing with the example on the right, let’s assume
that we are trying to set up a 4” SIN plate at a 30° angle
and need to know how tall the block underneath it should
be. If we multiply 0.5000 by 4, we know that we need to
use a 2” block.
The parentheses softkeys can be used to group calculations within an arithmetic equation. For
example,
2 + 1 ÷ 16 equals 2.0625, but (2 + 1) ÷ 16 equals 0.1875.
The parentheses are not always displayed during the keystroke sequence, but they are remem-
bered by
MILLPWR as it calculates the correct answer.
