Scientific calculations
Scientific calculations are used in the COMP mode.
Select [MODE/SET UP][1] (COMP).
Angle calculations
To set an initial angular value (Deg, Rad, Grad), press [2ND][MODE/SET UP]
and select the required angular unit in the menu in which you want to display
the results.
The following relationship exists between the angular units:
p
180° = rad = 200 grad
Angle conversions:
1. Set the required angular unit (Deg is set by default).
2. Enter the value.
3. Press [2ND][DRG►] to display the menu of units for conversion:
° (degrees), r (radians), g (gradians).
4. Select the unit for conversion and press [=].
Conversions between sexagesimal and decimal system
Calculations can be performed in the sexagesimal system (degrees, minutes
and seconds) and values can be converted between the sexagesimal and
decimal system by means of [DMS].
When inserting data in the sexagesimal system, always separate degrees,
minutes and seconds by pressing [DMS] and the following will display on the
screen 125°45'30". Upon repeated pressing of [DMS], you can switch between
the display in the sexagesimal and decimal system.
Conversions of coordinates
The calculator enables performing conversions between rectangular and polar
coordinates by means of the keys [2ND][POL] and [2ND][REC].
Note: Check whether the calculator is switched to the required angular units
during the calculation.
Goniometric functions and cyclometric functions
The Rebell SC2060S calculators enable calculating standard goniometric and
cyclometric functions such as sin, cos, tan, sin , cos , tan .
–1 –1 –1
Note: Check whether the calculator is switched to the required angular units
during the calculation.
Hyperbolic and inverse hyperbolic functions
The Rebell SC2060S calculators enable performing calculations of hyperbolic
and inverse hyperbolic functions such as sinh, cosh, tanh, sinh , cosh , tanh
–1 –1 –1
by pressing [HYP]. Press [HYP] to display a menu and a select a required
function by means of pressing a respective number.
Note: Check whether the calculator is switched to the required angular units
during the calculation.
Logarithmic and exponential functions
The calculator enables calculating natural and general logarithms and expo-
nents by using [log], [ln], [logax], [2ND][10
], [2ND][e ].
