E - 12
1. Change the default angle settings to the units you want to
convert to.
2. Enter the value of the unit to convert.
3. Press [ DMS ] to display the menu. The units you can
select are ° (degrees), ‘ (minutes), “ (seconds),
r
(radians)
,
g
(gradians) or


DMS (Degree-Minutes-Seconds).
4. Choose the units you are converting from.
5. Press [ ENTER ] twice.
• To convert an angle to DMS notation, select “


DMS ”, which converts an
entry to DMS notations, i.e., where 1

represents 1 degrees, 30
minutes, 0 seconds.
See Example 29.
• To convert a DMS notation to decimal, select ° (degrees), ‘ (minutes),
“ (seconds). See Example 30.
2 - 10 Trigonometric / Inverse-Tri. functions
• SRP-280 / SRP-285 provides standard trigonometric functions and
inverse trigonometric functions - sin, cos, tan, sin
–1
, cos
–1
and tan
–1
.
See Example 31.
(Note) : When using those keys, make sure the calculator is set for the
angle unit you want.
2 - 11 Hyperbolic / Inverse-Hyp. functions
• SRP-280 / SRP-285 uses [ 2nd ] [ HYP ] to calculate the hyperbolic
functions and inverse- hyperbolic functions - sinh, cosh, tanh, sinh
–1
,
cosh
–1
and tanh
–1
. See Example 32.
(Note) : When using those keys, make sure the calculator is set for the
angle unit you want.
2 - 12 Coordinates transformation
• Pressing [ 2nd ] [ R  P ] displays a menu to convert rectangular coordi-
nates to polar coordinates or vice versa. See Example 33.
Rectangular Coordinates Polar Coordinates
x + y i= r (cos θ + i sin θ)
