运用Linux嵌入式Python语言实现科学计算器 具有以下功能： 功能1:二进制，八进制，十进制，十六进制，四种格 式之间可以相互切换 功能2:加减乘除基本运算，平方、开方、x^y、x^3 等 功能3:tan、sin、cos、n!、log等请帮我编写具体的代码

以下是一个简单的例子，实现一个基本的科学计算器，包括二进制，八进制，十进制和十六进制之间的转换以及基本运算、平方、开方、x^y、x^3、tan、sin、cos、n!和log等功能。

    return int(octal, 8)

    return int(hex, 16)

def decimal_to_binary(decimal):
    return bin(decimal)[2:]

def decimal_to_octal(decimal):
    return oct(decimal)[2:]

def decimal_to_hex(decimal):
    return hex(decimal)[2:]

def add(x, y):
    return x + y

def subtract(x, y):
    return x - y

def multiply(x, y):
    return x * y

def divide(x, y):
    return x / y

def square(x):
    return x ** 2

def sqrt(x):
    return math.sqrt(x)

def power(x, y):
    return x ** y

def cube(x):
    return x ** 3

def tan(x):
    return math.tan(x)

def sin(x):
    return math.sin(x)

def cos(x):
    return math.cos(x)

def factorial(x):
    return math.factorial(x)

def log(x, base=10):
    return math.log(x, base)
