Calculations Using MATH Menu Items
The MATH menu contains functions used for more elaborate math concepts such as
trigonometry, logarithms, probability, and math unit/format conversions. The MATH menu
items may be incorporated into your expressions.
A Note about
The degree and radian systems are two of the basic methods
Degrees and
of measuring angles. There are 360 degrees in a circle, and "2-
Radians
pi" radians. 1 degree is equal to pi/180 radians. "Then, what's this
pi?", you may ask. Pi, or to use its symbol "π", is the ratio of the
circumference of a circle to its diameter. The value of π is the same
for any circle "3.14...", and it is believed to have an infinite number
of digits beyond the decimal point.
Note:
Please use "Degree" (DEG) for angle values and not GRAD because
this is used to represent Grads, where one turn comprises 400 Grads.
