解决方案 Python includes two functions in the math package; radians converts degrees to radians, and degrees converts radians to degrees. To match the output of your calculator you need: >>> math.cos(math.radians(
新建math_trig.py⽂件。 import math print('{:^7} {:^7} {:^7} {:^7} {:^7}'.format( 'Degrees', 'Radians', 'Sine', 'Cosine', 'Tangent')) print('{:-^7} {:-^7} {:-^7} {:-^7} {:-^7}'.format( '-', '-', '-', '-', '-')) fmt = '{:7.2f} {:7.2f}...
To use Python's trig functions, we need to introduce a concept:importing modules. In Python, there are many operations built into the language when the REPL or a Jupyter notebook starts. These operations include+,-,*,/like we saw in the previous post. However, not all functions will work...
If a function returns more than one value (like divmod) the values will be inserted in separate columns. The others are the regular BIF or math functions except for the trig functions for angles in degrees. You can also use "?" in a formula to get a random number. If you want the ...

Themathmodule includes three functions for converting floating point values to whole numbers. Each takes a different approach, and will be useful in different circumstances. The simplest istrunc(), which truncates the digits following the decimal, leaving only the significant digits making up the wh...
The SymPy functions symbols, Eq and solve are needed. We will also use NumPy's trig functions to solve this problem. In [6]: import numpy as np from sympy import symbols, Eq, solve Next, define the symbolic math variables. Multiple symbolic math variables can be defined at the same ...

主要应用于测试代码,如果其他模块调用这个模块,则不会调用此语句所包含的逻辑代码(测试用的代码);其中__name__属性(built-inmodel)表示存储的模块是如何被执行的。如: (1)如果执行当前模块,则其值为“__main__”; (2)如果是被引用进来的,就显示被引用的路径。
