Identify the function y = \tan\left(e^{-x^3}\right). We need to find its derivative with respect to x.
Recognize that this is a composite function, where the outer function is \tan(u) and the inner function is u = e^{-x^3}. We will use the chain rule to differentiate.
Differentiate the outer function \tan(u) with respect to u, which gives \sec^2(u).
Differentiate the inner function u = e^{-x^3} with respect to x. This requires using the chain rule again: differentiate e^{-x^3} to get -3x^2 \cdot e^{-x^3}.
Combine the derivatives using the chain rule: multiply \sec^2(e^{-x^3}) by the derivative of the inner function, -3x^2 \cdot e^{-x^3}, to get the derivative of the original function.
