Citizen SRP-145N manual Fraction Calculation, Trigonometric / Inverse Tri. Functions

Before performing the following calculation, check to see that your calculator is fixed at 2 decimal disaply format.

Fraction Calculation

•By pressing [ 2ndF ] [→ de ], the displayed value will be converted to the improper fraction.

(Ex.) : 32 + 7 35 = 12415

2 [ a b		] 3 [ + ] 7 [a b		] 3 [a b		] 5 [ = ]	DEG
	c		c		c		8 ∪ 4 ┘15
[ 2ndF ] [→ de ]							DEG
							124 ┘15

•When a press of [ a b c ] key after the [ = ] key or a fraction performed with a decimal, the answer is displayed as a decimal.

(Ex.) : 5

Trigonometric / Inverse – Tri. Functions

(Ex.) : 3 sin 30 ∘= 1.50

3 [ x ] 30 [ sin ] [ = ]

(Ex.) : cos ( 23π rad) = – 0.5

DEG 1.50

2 [ x ] [ 2ndF ] [ π] [ ⎟ ] 3 [ = ] [ cos ]	RAD	– 0.50
(Ex.) : sin –10.5 = 30 (deg)
0.5 [ 2ndF ] [ sin –1]	DEG 30.00
(Ex.) : cos –1( 1 ) = 0.79 (rad)

2 [ √ ] [ 2ndF ] [ 1/x ] [ 2ndF ] [ cos –1]

RAD 0.79

Hyperbolic Functions and Inverse – Hyp. Functions

(Ex.) : cosh 1.5 + sinh 1.5 = 4.48

1.5 [ 2ndF ] [ HYP ] [ cos ] [ + ]		DEG
		4.48
1.5 [ 2ndF ] [ HYP ] [ sin ] [ = ]
(Ex.) : sinh –17 = 2.64
7 [ 2ndF ] [ HYP ] [ 2ndF ] [ sin –1]		DEG
		2.64
