Version 1.2.8 is available!

Version 1.2.8 is mostly a bug fix release. In particular, the latest versions of
the Internet Explorer and Edge refused to handle touch input in `sketchometry`.

Further, we are very happy that `sketchometry` is now available in Arabic.

There is a small change in the input language for texts and function plots. Starting with this release, function names consisting of more than one letter are spelled with lower letters, only.

Here is a list of available functions:

Name | Description |
---|---|

cos(x) | Cosine of x |

cosh(x) | Hyperbolic cosine of x |

pow(e, b) | b to the power of e |

log(x), ln(x) | Natural logarithm |

log(x, b) | Logarithm to base b |

log2(x), lb(x) | Logarithm to base 2 |

log10(x), ld(x) | Logarithm to base 10 |

tan(x) | Tangent of x |

sqrt(x) | Square root of x |

ceil(x) | Get smallest integer n with n > x |

abs(x) | Absolute value of x |

max(a, b, c, …) | Maximum value of all given values |

min(a, b, c, …) | Minimum value of all given values |

exp(x) | EULER e to the x |

atan2(y, x) | Returns the arctangent of the quotient of its arguments |

random(max = 1) | Generate a random number between 0 and max |

round(v) | Returns the value of a number rounded to the nearest integer |

floor(x) | Returns the biggest integer n with n < x |

asin(x) | Arcsine of x |

acos(x) | Arccosine of x |

atan(x) | Arctangent of x |

sin(x) | Sine of x |

sinh(x) | Hyperbolic sine of x |

factorial(n) | Calculates factorial n! |

trunc(v, p = 0) | Truncate v after the p-th decimal |

D(f(x)), D(f(t),t) | Derivative of the function f of x (x is the default variable name) |

V(s) | Returns the value of the given element, e.g. sliders and angles |

L(s) | Calculates the length of the given segment |

X(P) Y(P) | Returns the x resp. y coordinate of the given point |

dist(P, Q) | Compute the distance of two points |

deg(A, B, C) | Calculate the angle of three points in degree |

rad(A, B, C) | Calculate the angle of three points in rad |
