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.

R–P

P–R

Degrees/Minutes/Seconds

You can perform calculations using degrees, minutes, and seconds, and convert between

sexagesimal and decimal values.

Example:

Keystrokes

2.5p

Press x

10x15x12xO4p

30qc

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).

P–R

60p

Sin-1

h OR

Sin-1

h (= 4.094622224)

This gives you the x value.

This gives you the y value.
