Python | sympy.evalf() method Last Updated : 18 Jun, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report 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. Python3 1=1 # Import sympy from sympy import * # Use sympy.evalf() method expn = sqrt(9) gfg = expn.evalf() print(gfg) Output : 3.00000000000000 Example #2 : Python3 1=1 # Import sympy from sympy import * # Use sympy.evalf() method expn = sqrt(9)*cos(45) gfg = expn.evalf() print(gfg) Output : 1.57596596645319 Comment More infoAdvertise with us Next Article Python | sympy.evalf() method J jitender_1998 Follow Improve Article Tags : Python SymPy Practice Tags : python Similar Reads Python | sympy.eigenvals() method With the help of sympy.eigenvals() method, we can find the eigenvalues of a matrix by using sympy.eigenvals() method.
