Adding a constant to a function does not change its derivative because the derivative of a constant is zero. When differentiating a sum, the constant term vanishes, leaving the derivative of the original function unchanged.

Conditions: The function is differentiable.; The added term is a constant (e.g., 1, $\pi$, or $C$).
