函數 Trigonometric sine function Trigonometric cosine function Trigonometric tangent function Trigonometric cotangent function Arcsine - inverse sine function Arccosine - inverse cosine function Arctangent - inverse tangent function Arccotangent - inverse cotangent function Natural logarithm - logarithm to base e Decadic logarithm - logarithm to base 10 Logarithm - logarithm the specified base Exponential function Square root function Cubic root function Gives absolute value of an argument Gives the sign of an argument: -1 if argument is less than 0, 0 if equals to 0, 1 if more than 0 Equals function - gives 1 if two arguments are equals, 0 otherwise Lesser-or-equals function - gives 1 if two arguments are equals or first is less than second, 0 otherwise Greater-or-equals function - gives 1 if two arguments are equals or first is greater than second, 0 otherwise Not-equals function - gives 1 if two arguments are not equals, 0 otherwise Lesser function - gives 1 if first argument is less than second, 0 otherwise Greater function - gives 1 if first argument is greater than second, 0 otherwise Converts degrees into radians: d - degrees, m - minutes (default = 0), s - seconds (default = 0) Converts degrees from DMS notation to decimal notation: d - degrees, m - minutes (default = 0), s - seconds (default = 0) Converts radians into degrees 三角函數 雙曲函數 比較函數 常用函數 自訂函數
