Basic examples that show how to use the chain rule to calculate the derivative of the composition of functions. Integration by substitution is just the reverse chain rule. \begin{aligned} \displaystyle \frac{d}{dx} \cos{3x^3} &= -\sin{3x^3} \times \frac{d}{dx} (3x^3) \\ &= -\sin{3x^3} \times 9x^2 \\ &= -9x^2 \sin{3x^3} \\ \end{aligned} \\ (b)    Integrate $$x^2 \sin{3x^3}$$. By recalling the chain rule, Integration Reverse Chain Rule comes from the usual chain rule of differentiation. There are several such pairings possible in multivariate calculus, involving a scalar-valued function u and vector-valued function (vector field) V . by the Chain Rule, dy/dx = dy/dt × dt/dx so dy/dx = 3t² × 2x = 3(1 + x²)² × 2x = 6x(1 + x²) ². That is, if f and g are differentiable functions, then the chain rule expresses the derivative of their composite f ∘ g — the function which maps x to $${\displaystyle f(g(x))}$$— in terms of the derivatives of f and g and the product of functions as follows: We call it u-substitution. In this section we discuss one of the more useful and important differentiation formulas, The Chain Rule. The temperature is lower at higher elevations; suppose the rate by which it decreases is 6 ∘ C {\displaystyle 6^{\circ }C} per kilometer. Which is essentially, or it's exactly what we did with u-substitution, we just did it a little bit more methodically with u-substitution. You'll need to know your derivatives well. The chain rule (function of a function) is very important in differential calculus and states that: (You can remember this by thinking of dy/dx as a fraction in this case (which it isn’t of course!)).
