NCERT Class 12 Maths · Chapter 7 Integrals · Exercise 7.6 Question 23

Evaluate \(\int x^{2} e^{x^{3}}\, dx\).

💡 Concept Hints

  1. Identify the domain and the inner and outer functions, or the relevant one-sided limits.
  2. Apply the appropriate differentiation or limit rule, keep all chain factors, and check exceptional points.

✅ Step-by-Step Solution

Final Answer: A: \(\frac{e^{x^{3}}}{3}\) + C.
  1. Work on each open interval where the original integrand is real and defined.
  2. Put u=x³, du=3x²dx; integrate eᵘdu/3.
  3. An antiderivative is F(x)=\(\frac{e^{x^{3}}}{3}\).
  4. Differentiate this expression to check that F′(x)=\(x^{2} e^{x^{3}}\). Add an arbitrary constant C on each domain component.
