This code is a library for calculating derived functions.
To install the library, use pip:
pip install pyderivative==1.2
To use the library, import the Derivative
class from the library:
from pyderivative.Derivative import Derivative
Then you can create an instance of the Derivative
class by passing the function you want to differentiate as an argument:
def func(x):
return x**2
derivative = Derivative(func)
Calculates the derivative of the function at the point x0
using the Taylor method.
Usage example:
result = derivative.tailor_app(2)
Calculates the derivative of the function at the point x0
using the polynomial method.
Usage example:
result = derivative.polinom_app(2)
Calculates the second derivative of the function at the point x0
.
Usage example:
result = derivative.second_derivative(2)
Calculates the first or second derivative of a function at the point x0
using the three-point method.
Usage example:
result = derivative.threepoint_pattern(2, second_deriv=True)
If the function was set using a grid, the methods tailor_app
, polinom_app
and threepoint_pattern
will throw an exception. If an error occurred while using the function, the methods will also throw an exception.
