FUN TON' K YS
Select~, the entry and dtsplay un1ts for the trigonometnc
functtons. To convert from DEGREES (RADIANS) to RADIANS
(DEGRE:ES):
1) SET: DEGREES (RADIANS)
2) E NTER: DEGREES (RADIANS)
3) PRESS: sin x , cos x, tan x
4) SET: RADIANS (DEGREES)
5) PRESS: a~c sin x, cos x. or tan x; answer in RADIANS
(DEGREES) 1s entered mto the X reg1ster.
Inverse~ tngonometnc functtons are calculated for the prin-
ctpal value
of the function.
