types.symbolic.SymbolicExpression
Single symbolic expression.
Any SymPy expression representing a mathematical formula.
>>> import sympy as sp
>>> x, u = sp.symbols('x u')
>>> expr: SymbolicExpression = x**2 + sp.sin(u)
>>>
>>> # Differentiate
>>> dexpr_dx = sp.diff(expr, x) # 2*x
>>>
>>> # Evaluate
>>> result = expr.subs({x: 1.0, u: 0.0}) # 1.0
>>>
>>> # Simplify
>>> simplified: SymbolicExpression = sp.simplify(expr)# types.symbolic.SymbolicExpression { #cdesym.types.symbolic.SymbolicExpression }
