With the help of sympy.evalf() method, we are able to evaluate the mathematical expressions.
Syntax :
sympy.evalf()
Return : Return the evaluated mathematical expression.
Example #1 :
In this example we can see that by using sympy.evalf() method, we are able to evaluate the mathematical expressions.
# Import sympy from sympy import * # Use sympy.evalf() method expn = sqrt(9) gfg = expn.evalf() print(gfg) |
Output :
3.00000000000000
Example #2 :
# Import sympy from sympy import * # Use sympy.evalf() method expn = sqrt(9)*cos(45) gfg = expn.evalf() print(gfg) |
Output :
1.57596596645319
