Python math.acosh()方法 (Python math.acosh() method)
math.acosh() method is a library method of math module, it is used to get the hyperbolic arc cosine of the given number in radians, it accepts a number and returns hyperbolic arc cosine.
math.acosh()方法是數學模塊的庫方法,用于獲取以弧度為單位的給定數字的雙曲反余弦,它接受一個數字并返回雙曲反余弦。
Note: math.acosh() method accepts only numbers (positive integer or float greater than or equal to 1), if we provide a negative value it returns a ValueError – "ValueError: math domain error", and if we provide anything else except the number, it returns error TypeError – "TypeError: a float is required".
注意: math.acosh()方法僅接受數字(正整數或浮點數大于或等于1),如果我們提供負值,它將返回ValueError – “ ValueError:math domain error” ,并且如果我們提供其他內容,則除外數字,它返回錯誤TypeError – “ TypeError:需要浮點數” 。
Syntax of math.acosh() method:
math.acosh()方法的語法:
math.acosh(x)Parameter(s): x – is the number whose hyperbolic arc cosine to be calculated.
參數: x –是要計算其雙曲反余弦的數字。
Return value: float – it returns a float value that is the hyperbolic arc cosine value of the number x.
返回值: float-它返回一個浮點值,該值是數字x的雙曲反余弦值。
Example:
