1. The problem is to understand how the integrand was derived step by step. 2. An integrand is the function inside an integral sign that we want to integrate. 3. To find the integrand, we start from the original function or expression given before integration. 4. If the problem involves differentiation or substitution, we apply those rules carefully to rewrite the function. 5. For example, if the integral is $$\int f(g(x)) g'(x) \, dx$$, the integrand is $$f(g(x)) g'(x)$$. 6. If substitution is used, say $$u = g(x)$$, then $$du = g'(x) dx$$, and the integrand changes accordingly. 7. Always simplify the expression inside the integral to get the integrand clearly. 8. If you provide the original function or integral, I can show the exact step-by-step derivation of the integrand.
