Pythonで学び直す高校数学

Last updated at Posted at 2021-11-13

Pythonで学び直す高校数学では、Jupyter Notebookをつかってましたが、Google Colabでやってみます。
https://colab.research.google.com

まずは準備。y=x^2+2x+1のグラフを描いてみます。

>>>from sympy import *
>>>(x,y)=symbols('x y')
>>>y = x**2 + x*2 + 1
>>>plot(y,(x,-10,10),ylabel='y',ylim=(-10,10))

べき乗。

>>>10 ** 3
1000
>>>10 ** 0
1
>>>10 ** -2
0.01

2/16進数。

>>>bin(10)
'0b1010'
>>>bin(-10)
'-0b1010'
>>>bin(-10 & 0xFF)
'0b11110110'
>>>hex(10)
'0xa'
>>>hex(-10 & 0xFF)
'0xf6'

実数/商/余。

>>>10 / 3
3.3333333333333335
>>>10 // 3
3
>>>10 % 3
