16.3 Trigonometry
Octave provides the following trigonometric functions. Angles are
specified in radians. To convert from degrees to radians multipy by
pi/180
(e.g. sin (30 * pi/180) returns the sine of 30 degrees).
- Mapping Function: sin (z)
-
- Mapping Function: cos (z)
-
- Mapping Function: tan (z)
-
- Mapping Function: sec (z)
-
- Mapping Function: csc (z)
-
- Mapping Function: cot (z)
- The ordinary trigonometric functions.
- Mapping Function: asin (z)
-
- Mapping Function: acos (z)
-
- Mapping Function: atan (z)
-
- Mapping Function: asec (z)
-
- Mapping Function: acsc (z)
-
- Mapping Function: acot (z)
- The ordinary inverse trigonometric functions.
- Mapping Function: sinh (z)
-
- Mapping Function: cosh (z)
-
- Mapping Function: tanh (z)
-
- Mapping Function: sech (z)
-
- Mapping Function: csch (z)
-
- Mapping Function: coth (z)
- Hyperbolic trigonometric functions.
- Mapping Function: asinh (z)
-
- Mapping Function: acosh (z)
-
- Mapping Function: atanh (z)
-
- Mapping Function: asech (z)
-
- Mapping Function: acsch (z)
-
- Mapping Function: acoth (z)
- Inverse hyperbolic trigonometric functions.
Each of these functions expect a single argument. For matrix arguments,
they work on an element by element basis. For example,
| | sin ([1, 2; 3, 4])
=> 0.84147 0.90930
0.14112 -0.75680
|
- Mapping Function: atan2 (y, x)
- Return the arctangent of y/x. The signs of the arguments
are used to determine the quadrant of the result, which is in the range
pi to -pi.
