FX 300 MS Training guide Trigonometry Trigonometric/Inverse Trigonometric Functions You can use sin, cos and tan to calculate and solve trigonometric equations. Examples (in degree mode): Keystrokes [sin] [30] [=] [SHIFT] [sin] [.5] [=] Display 0.5 30 Hyperbolic/Inverse Hyperbolic Functions Examples (in degree mode): Keystrokes [hyp] [sin] [3.6] [=] [SHIFT] [hyp] [sin] [30] [=] Or [hyp] [SHIFT] [sin] [30] [=] Display 18.28545536 4.094622224 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) 6 References the Casio FX-300 MS User's Guide Casio FX-300MS Scientific calculator
