Python求极限求积分，编程实现

在PyCharm中编程实现求解极限和积分运算

1.求极限

#!/usr/bin/env python
# -*- coding: UTF-8 -*-
from sympy import *
n = Symbol('n')
s = ((n+3)/(n+2))**n
print(limit(s, n, oo))

结果输出 ： E

2求定积分

#!/usr/bin/env python
# -*- coding: UTF-8 -*-
from sympy import *
t = Symbol('t')
x = Symbol('x')
m = integrate(sin(t)/(pi-t),(t,0,x))
n = integrate(m,(x,0,pi))
print (n)

结果：2
