2 min readTo specify a non-negative real number in sympy, you can use the sympy.symbols function to define a symbol and then impose the condition that it is non-negative using the sympy.sympy.functions.elementary.integers function. For example, you can create a non-negative real number symbol x as follows: import sympy x = sympy.

5 min readTo get a range between 0 and a specific number in PowerShell, you can use the following code: $number = 10 $range = 0..$number This code will create an array called $range that contains all integers from 0 to the specified number (in this case, 10). You can change the value of $number to adjust the range according to your requirements. Just remember that the range will include both the starting value (0) and the ending value (specified number).

3 min readSympy, a Python library for symbolic mathematics, sometimes simplifies expressions by deleting repeated values or terms. To prevent sympy from deleting the same values, you can use the simplify function with the keyword argument rational=False. This will prevent sympy from simplifying expressions into fractions or other simplified forms. Additionally, you can use the expand function to expand expressions and see all the terms separately without combining them.
-
5 min readTo substitute values in a SymPy object, you can use the subs() method. This method allows you to substitute specific values for symbols or variables in your expression. For example, if you have an expression x**2 + y and you want to substitute the value of x with 2 and y with 3, you can do so using the subs() method like this: expr.subs({x: 2, y: 3}). The subs() method returns a new expression with the substituted values.

4 min readTo control the float number precision in SymPy, you can use the mpmath library which is integrated with SymPy. You can change the precision by setting the mp.dps attribute to the desired number of decimal places. For example, to set the precision to 10 decimal places, you can use mp.dps = 10. This will affect all floating point calculations in SymPy. Additionally, you can use the evalf() method with the n argument to specify the number of decimal places you want for a specific calculation.
-
3 min readTo list all SymPy symbols, you can use the sympy.symbols() function which allows you to create symbols in bulk. For example, you can use sympy.symbols('x y z') to create symbols x, y, and z. If you want to list all the created symbols, you can use the symbols() function without any arguments to return a list of all symbols that have been defined. This will give you a list of all the symbols that you have created using the SymPy library.
-
3 min readTo change a real symbol to a complex symbol in SymPy, you can use the I symbol to represent the imaginary unit. For example, if you have a real symbol x, you can create a complex symbol z by assigning it as z = x + I*y where y is another real symbol. This will make z a complex symbol with both real and imaginary parts. You can then perform operations with this complex symbol in SymPy as needed.
-
5 min readTo integrate a max function using Sympy in Python, you can use the Piecewise function to define the max function as a piecewise function. This allows you to express the max function as a combination of different functions over different intervals. Then you can use the integrate function from Sympy to integrate the max function over a specific range. The integrate function will handle the integration of the piecewise function and give you the result.

5 min readTo convert a Python list into a SymPy Add class, you can first create a SymPy symbol or constant for each element in the list. Then, you can use the Add function from the SymPy library to add these symbols or constants together to create your desired expression. This will allow you to manipulate the expression further using SymPy's powerful algebraic capabilities.[rating:b1c44d88-9206-437e-9aff-ba3e2c424e8f]What tools can assist in the conversion of a Python list to a sympy add class.

5 min readTo remove the "o()" term in a series from SymPy, you can use the removeO() function. This function helps to simplify and clean up the series representation by removing the terms with the order of the specified variable. For example, if you have a series expression like series = x + x2 + O(x3), you can remove the "o()" term by calling the removeO() function on the series object: series.removeO(). This will give you a simplified expression without the higher order terms.

4 min readTo make axes be the right length in a plot of sympy, you can adjust the range of the axes by setting the xmin, xmax, ymin, and ymax values when creating the plot. This will ensure that the axes are of the desired length and scale. Additionally, you can also adjust the size of the plot itself to make sure that the axes are visually balanced and properly sized. By customizing the axis range and plot size, you can create a plot with axes that are the right length for your specific needs.
