With the help of sympy.logcombine()
, we can combine the log terms in the mathematical expression by using the following properties that are listed below.
Properties :
1) log(x*y)=log(x)+log(y)
2) log(x**n)=nlog(x)
Syntax : sympy.logcombine()
Return : Return the simplified mathematical expression.
Example #1 :
In this example we can see that by using sympy.logcombine()
, we are able to combine the log terms in mathematical expression.
from sympy import *
x, y, z = symbols( 'x y z' , positive = True )
gfg_exp = log(x) + log(y)
gfg_exp = logcombine(gfg_exp)
print (gfg_exp)
|
Output :
log(x*y)
Example #2 :
from sympy import *
x, y, z = symbols( 'x y z' , positive = True )
gfg_exp = 5 * log(x)
gfg_exp = logcombine(gfg_exp)
print (gfg_exp)
|
Output :
log(x**5)
