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 = Grads (Gra)
Trigonometric/Inverse Trigonometric Functions
To calculate the sine, cosine, or tangent of the displayed angle.
Example (in degree mode): [30] [sin]
To calculate the arcsine, arccosine, or arctangent.
Example (in degree mode): [.5] [SHIFT] [sin]
Hyperbolic/ Inverse Hyperbolic Functions
To calculate the hyperbolic sine, cosine, or tangent of the displayed angle.
Example (in degree mode): [3.6] [hyp] [sin]
To calculate the hyperbolic arcsine, arccosine, or arctangent of the displayed angle.
Example (in degree mode): [30] [hyp] [SHIFT] [sin
Coordinate Conversion
You can convert between rectangular and polar coordinates.
Make sure you are using the correct angle unit (D, R, G) before starting your calculation.
[SHIFT] [R-P] Rectangular to polar coordinate conversion
[SHIFT] [P-R] Polar to rectangular coordinate conversion
[SHIFT] [X-Y] Use this operation to switch between the two coordinates produced by the
Degrees/Minutes/Seconds
You can perform calculations using degrees, minutes, and seconds, and convert
between sexagesimal and decimal values.
