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)
