Trigonometric/Inverse Trigonometric Functions; Hyperbolic/Inverse Hyperbolic Functions; Coordinate Conversion - Casio fx 260 Training Manual

CASIO FX 260 SOLAR SCIENTIFIC CALCULATOR
TRIGONOMETRY
Be sure to select the angle unit (D,R,G) you want to use before beginning
a calculation.
Mode 4 = Degrees (Deg)
Mode 5 = Radians (Rad)
Mode 6 = Grad s (Gra)

Trigonometric/Inverse Trigonometric Functions

To calculate the sine, cosine, or tangent of the displayed angle.
Example: (in degree mode): 30j (= .5)
To calculate the arcsine, arccosine, or arctangent
Example: (in degree mode):.5qj (= 30)

Hyperbolic/Inverse Hyperbolic Functions

To calculate the hyperbolic sine, cosine, or tangent of the displayed angle.
Example: (in degree mode): 3.6cq (= 18.28545536)
To calculate the hyperbolic arcsine, arccosine, or arctangent of the displayed angle.
Example: (in degree mode): 30cq

Coordinate Conversion

You can convert between rectangular and polar coordinates.
Make sure you are using the correct angle unit (D,R,G) before staring your calculation.

Degrees/Minutes/Seconds
You can perform calculations using degrees, minutes, and seconds, and convert between
sexagesimal and decimal values.

Rectangular to polar coordinate conversion
Polar to rectangular coordinate conversion
Use this operation to switch between the two coordinates produced by
the conversion operation.
Example: To convert polar coordinates (r = 2, θ = 60) to rectangular
coordinates (x, y).

h (= 4.094622224)
This gives you the x value.
This gives you the y value.
