∏ Calculations
Y
ou can obtain the product of an input f(x) expression for a specific range.
The calculation formula is:
(f(x)) = f(a) × f(a
+ 1) × f(a + 2) × ⋯ × f(b).
The Natural Display input syntax is
(f(x)), while Linear Display input
syntax is ∏(f(x), a, b).
a
and b are integers in the range of a < 1 × 10
10
, b
< 1 × 10
10
, a ≦ b.
Example: (x + 1) = 720
(MthIO-MathO)
( ) (X) 1 1 5 720
(LineIO)
( ) (X) 1 (,) 1
(,) 5
720

Rectangular-Polar Coordinate
Conversion
Pol converts rectangular coordinates to polar coordinates, while Rec
converts polar coordinates to rectangular coordinates.
