Solve sin(x^3)

$$\sin ( { x }^{ 3 } )$$

Differentiate w.r.t. x

$$3x^{2}\cos(x^{3})$$

Steps Using Chain Rule

If F is the composition of two differentiable functions f\left(u\right) and u=g\left(x\right), that is, if F\left(x\right)=f\left(g\left(x\right)\right), then the derivative of F is the derivative of f with respect to u times the derivative of g with respect to x, that is, \frac{\mathrm{d}}{\mathrm{d}x}(F)\left(x\right)=\frac{\mathrm{d}}{\mathrm{d}x}(f)\left(g\left(x\right)\right)\frac{\mathrm{d}}{\mathrm{d}x}(g)\left(x\right).

$$\cos(x^{3})\frac{\mathrm{d}}{\mathrm{d}x}(x^{3})$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$$\cos(x^{3})\times 3x^{3-1}$$

Simplify.

$$3x^{2}\cos(x^{3})$$

Evaluate
