解方程组  2*x-y=3，3*x+y=7

复制代码from sympy import * x=Symbol('x') y=Symbol('y') print solve([2*x-y-3,3*x+y-7],[x,y])# result is: {x: 2, y: 1}

from sympy import *
x=Symbol('x') 
y=Symbol('y') 
print solve([2*x-y-3,3*x+y-7],[x,y])
# result is: {x: 2, y: 1}

求积分  ((n+3)/(n+2))**n，limit n->oo

复制代码from sympy import * n=Symbol('n') s=((n+3)/(n+2))**n print limit(s,n,oo) # result is:
