In Calculus, we can use the **product** **rule** formula to calculate the derivative or evaluate the **differentiation** **of** the **product** **of** two functions. The **product** **rule** formula is as follows: d d x f ( x) = d d x { u ( x). v ( x) } = [ v ( x) × u ′ ( x) + u ( x) × v ′ ( x)] Where, f (x) = Sum of the differentiable functions u (x) and v (x) (x).

Ferroptosis is an iron-dependent lipid peroxidative form of cell death that is distinct from apoptosis and necrosis. ALOX15, also known as arachidonic acid 15-lipoxygenase, promotes ferroptosis by converting intracellular unsaturated lipids into oxidized lipid intermediates and is an important ferroptosis target.

The **proof** **of** this theorem uses the definition of differentiability of a function of two variables. Suppose that f is differentiable at the point P(x0, y0), where x0 = g(t0) and y0 = h(t0) for a fixed value of t0. We wish to prove that z = f (x(t), y(t)) is differentiable at t = t0 and that Equation 14.5.1 holds at that point as well.

One of the two basic operations of calculus is **differentiation**.. **Differentiation** finds the slope of a function f(x) at one point.This produces a new function known as the derivative:.
