Euler's Method approximation in Python.
Import the library, then call the evaluate method to generate a table of data.
Call the print method to print out the points to the console.
Call the graph method to graph the equation.
Parameters:
- Derivative expression
- Starting X
- Starting Y
- Ending X
- Step size
Example:
import euler
calc = euler.EulerCalculator()
points = calc.evaluate(
derivative="x-2ysin(x)", startX=0, startY=20, endX=2, stepSize=0.1
)
calc.print(points)
calc.graph(points)Output:
