Python | sympy.is_polynomial() method Last Updated : 26 Jul, 2019 Comments Improve Suggest changes Like Article Like Report With the help of sympy.is_polynomial() method, we can check if polynomial is found it will return True as boolean value by using sympy.is_polynomial() method. Syntax : sympy.is_polynomial() Return : Return a boolean value if polynomial is found. Example #1 : In this example we can see that by using sympy.is_polynomial() method, we are able to detect the polynomial by getting boolean value. Python3 1=1 # import sympy from sympy import * x, y = symbols('x y') # Use sympy.is_polynomial() method gfg = simplify(x**2 + 2 * y*x + y**2).is_polynomial() print(gfg) Output : True Example #2 : Python3 1=1 # import sympy from sympy import * x, y = symbols('x y') # Use sympy.is_constant() method gfg = simplify(sin(x)).is_constant() print(gfg) Output : False Comment More infoAdvertise with us Next Article Python | sympy.is_polynomial() method J jitender_1998 Follow Improve Article Tags : Python SymPy Practice Tags : python Similar Reads Python | sympy.as_poly() method With the help of sympy.as_poly() method, we can make the mathematical function into a polynomial object by using sympy.as_poly() method.

A polygon is said to be convex if all its interior angles are less than 180 degrees and there are no intersections between the sides. Syntax: Polygon.is_convex() Returns: True: True if this polygo 1 min read Like
