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).

Example 1 : find the differentiation of sinx cosx. Solution : Let sinx = f (x) and g (x) = cosx. Then, by using product rule in differentiation, d d x {f (x) g (x)} = d d x (f (x)) g (x) + f (x). d d x (g (x)) d d x [sinx.cosx] = d d x (sinx) cosx + sinx. d d x (cosx) = cosx cosx + sinx (-sinx) = c o s 2 x - s i n 2 x. = cos2x. I know how to prove the product rule for differentiation by using the definition for derivatives, i.e you "add zero" and collect terms. Yesterday a friend showed me another proof that involves the logarithm, implicit differentiation and the chain rule but after looking at it for a while I started to ask myself some questions about the proof..

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.

The differentiation of trigonometric functions is the mathematical process of finding the derivative of a trigonometric function, or its rate of change with respect to a variable.For example, the derivative of the sine function is written sin′(a) = cos(a), meaning that the rate of change of sin(x) at a particular angle x = a is given by the cosine of that angle.

Differentiation finds the slope of a function f(x) at one point.This produces a new function known as the derivative:. The notations df/dx and f'(x) for the derivative are common, but here we want to emphasise that the derivative is really an operator.Unlike a function, which takes a number and returns another.
