Prolog - Scientific Predicates
Following are the scientific predicates −
| Predicates | Description |
|---|---|
| sin(X). | Sine of X where X is in radians. |
| cos(X). | Cosine of X where X is in radians. |
| tan(X). | Tangent of X where X is in radians. |
| asin(X). | Arcsine of X where X is in radians. |
| acos(X). | Arccosine of X where X is in radians. |
| atan(X) | Arctangent of X where X is in radians. |
| sinh(X) | Hyperbolic Sine of X where X is in radians. |
| cosh(X). | Hyperbolic Cosine of X where X is in radians. |
| tanh(X) | Hyperbolic Tangent of X where X is in radians. |
| asinh(X). | Hyperbolic Arcsine of X where X is in radians. |
| acosh(X) | Hyperbolic Arccosine of X where X is in radians. |
| atanh(X) | Hyperbolic Arctangent of X where X is in radians. |
| log(X) | Log of X |
| log10(X) | Log10 of X |
| exp(X) | Exponential of X |
Now let us see some of these functions in action using Prolog programs.
Example
| ?- X is sin(0) . X = 0.0 yes | ?- X is sin(1). X = 0.8414709848078965 yes | ?- X is cos(0). X = 1.0 yes | ?- X is cos(1). X = 0.54030230586813977 yes | ?- X is tan(0). X = 0.0 yes | ?- X is tan(1). X = 1.5574077246549023 yes | ?-
Example
| ?- X is asin(1). X = 1.5707963267948966 yes | ?- X is sinh(1). X = 1.1752011936438014 yes | ?- X is asinh(1). X = 0.88137358701954305 yes | ?-
Example
| ?- X is log(10). X = 2.3025850929940459 yes | ?- X is log10(10). X = 1.0 yes | ?- X is exp(2). X = 7.3890560989306504 yes | ?-
