By pressing [ 2nd ] [
d
/
c
], the displayed value will be converted to
the improper fraction and vice versa. To convert between a deci-
mal and fractional result, press [a
b
/
c
] .See Example 18.
•
Calculations containing both fractions and decimals are calculated
in decimal format. See Example 19.
Angle units conversion
The angle units (DEG, RAD, GRAD) is set by pressing [ MODE ] to
display the angle menu. The relation among the three angle units is :
180° = π rad = 200 grad
Angle conversions ( See Example 20.) :
1. Change the default angle settings to the units you want to con-
vert to.
2. Enter the value of the unit to convert.
3. Press [ DRG→ ] to display the menu.
D R G
1 2 3
The units you can select are D(degrees),
R(radians), G(Gradians).
4. Choose the units you are converting from.
5. Press [ = ].
Trigonometric / Inverse-Tri. functions
•
SR-270ll
/
SR-275
provides standard trigonometric functions and
inverse trigonometric functions - sin, cos, tan, sin
–1
, cos
–1
and tan
–
1
. See Example 21.
(Note) : When using those keys, make sure the calculator is set for
the angle unit you want.
Hyperbolic / Inverse-Hyp. functions
•
SR-270ll
/
SR-275
uses [ 2nd ] [ HYP ] to calculate the hyperbolic
functions and inverse- hyperbolic functions - sinh, cosh, tanh,
sinh
–1
, cosh
–1
and tanh
–1
. See Example 22.
(Note) : When using those keys, make sure the calculator is set for
the angle unit you want.
Sexagesimal Decimal transformation
Sexagesimal notation is as follow
12
Ƒ
59
Ƒ
45.6
Ƒ
Represent 12 Degree, 59 Minutes, 45.6 Seconds
•
The calculator can preform the conversion between decimal and
sexagesimal numbers by [ ] and [ 2nd ] [ ]. See Example 23.
