Trigonometry
Trigonometric/Inverse Trigonometric Functions
You can use sin, cos and tan to calculate and solve trigonometric equations.
Examples (in degree mode): |
|
Keystrokes | Display |
[sin] [30] [=] | 0.5 |
[SHIFT] [sin] [.5] [=] | 30 |
Hyperbolic/Inverse Hyperbolic Functions | |
Examples (in degree mode): |
|
Keystrokes | Display |
[hyp] [sin] [3.6] [=] | 18.28545536 |
[SHIFT] [hyp] [sin] [30] [=] | 4.094622224 |
Or |
|
[hyp] [SHIFT] [sin] [30] [=] |

Convert Radians to Degrees
To convert Radians to Degrees, put the calculator in Degree mode.
Example: π radians to degrees
Press [SHIFT] [π ] [SHIFT] [DRG] and press [2] for Radians [=] 180
To convert Degrees to Radians, put the calculator in Radian mode.
Example: | 180 degrees to radians |
| Press [180] [SHIFT] [DRG] and press [1] for Degrees [=] 3.141592654 |
Coordinate Conversion
You can convert from polar to rectangular and from rectangular to polar. The calculation results are automatically assigned to variables E and F. Note: For both examples, be sure you are in degree mode.
To convert polar coordinates (r, θ) to rectangular coordinates (x, y).
Example: To convert ( r = 2, θ = 60) to rectangular coordinates:
Press [SHIFT] [REC] [2] [ , ] [60] [ ) ] [=] | 1 (x value) |
[RCL] [F] | 1.732050808 (y value) |
To convert rectangular coordinates (x, y) to polar coordinates (r, θ).
Example: To convert ( x = 1, y = 
3 ) to rectangular coordinates:
Press [POL] [1] [ , ] [ | ] [3] [ ) ] [=] | 2 (r value) |
[RCL] [F] |
| 60 (θ value) |
