Hey Davud,
If you want to add differentiation to the expression trees, you'll need to modify the expressions.py file in the mathy_core repository.
You can find the relevant files here: https://github.com/mathy/mathy_core/blob/master/mathy_core/expressions.py
The older version of mathy_core had differentiation built-in to the expressions, so here's an example of what it might look like for the MultiplyExpression:
class MultiplyExpression(BinaryExpression):
"""Multiply one and two"""
def operate(self, one, two):
return one * two
# f(x) = g(x)*h(x)
# f'(x) = g(x)*h'(x) + g'(x)*h(x)
def differentiate(self, by_variable):
return AddExpression(
MultiplyExpression(self.left, self.right.differentiate(by_variable)),
MultiplyExpression(self.left.differentiate(by_variable), self.right),
)from mathy.
