How to Define an Inequality In Sympy?

2 minutes read

In SymPy, an inequality can be defined using the symbols, inequalities and logical operators provided by the library. To define an inequality in SymPy, you can use the symbols() function to create the variables involved in the inequality, such as x and y. Then, you can use the Eq() function to create the inequality expression, using the logical operators like <, <=, >, >= to compare the variables. For example, you can define an inequality x < 5 as Eq(x, 5) or x <= y as Eq(x, y). This way, you can create and manipulate inequalities in SymPy for various mathematical calculations and symbolic manipulations.


What is the representation of inequalities in sympy for calculations?

In sympy, inequalities are represented using symbols such as >, <, <=, >= for greater than, less than, less than or equal to, and greater than or equal to, respectively.


For example, to represent the inequality x > 5, you would write x > 5 in sympy.


These inequalities can be used in calculations and solving equations involving inequalities in sympy.


How to define an inequality in sympy using symbols?

To define an inequality in SymPy using symbols, you can use the symbols function to create symbolic variables and then use the Symbol objects to create the inequality.


Here is an example:

1
2
3
4
5
6
7
8
9
from sympy import symbols

# Define the symbols
x, y = symbols('x y')

# Define the inequality
inequality = x + y > 5

print(inequality)


This will output:

1
x + y > 5


You can also use the Symbol objects directly to create the inequality:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
from sympy import Symbol

# Create symbolic variables
x = Symbol('x')
y = Symbol('y')

# Define the inequality
inequality = x - y < 10

print(inequality)


This will output:

1
x - y < 10



What is an open-ended inequality in sympy?

An open-ended inequality in sympy is an inequality where the endpoint values are not included in the solution set. In other words, the variables in the inequality are not equal to the endpoint values.


For example, an open-ended inequality in sympy could be x > 3 or y < -2. In both cases, the solution set includes all real numbers greater than 3 or less than -2, respectively, but not including 3 or -2 themselves.


Open-ended inequalities can be solved and manipulated using sympy just like any other type of inequality.
