Before performing the following calculation, check to see that your
calculator is fixed at 2 decimal disaply format.
Fraction Calculation
• By pressing [ 2ndF ] [ d/e ], the displayed value will be converted
to the improper fraction.
(Ex.) :
15
124

• 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.

Trigonometric / Inverse – Tri. Functions
(Ex.) : 3 sin 30 ∘= 1.50
3 [ x ] 30 [ sin ] [ = ] DEG 1.50
(Ex.) : cos (
3
2 π
rad) = – 0.5
2 [ x ] [ 2ndF ] [ π] [ ÷ ] 3 [ = ] [ cos ]
RAD – 0.50
(Ex.) : sin –1 0.5 = 30 (deg)
0.5 [ 2ndF ] [ sin –1 ] DEG 30.00
(Ex.) : cos –1 (

Hyperbolic Functions and Inverse – Hyp. Functions
(Ex.) : cosh 1.5 + sinh 1.5 = 4.48
1.5 [ 2ndF ] [ HYP ] [ cos ] [ + ]
1.5 [ 2ndF ] [ HYP ] [ sin ] [ = ] DEG .
