Exercise · ZW-INDEFINITE-INTEGRAL-009 · ★★☆ Intermediate

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

Choose one option.

Show answer
  • D. \(e^{x^{2}}+C\)

Explanation

With \(u=x^{2}\), we have \(du=2x\,dx\), so the integral is \(\int e^{u}\,du=e^{u}+C\).

Review the concept: Indefinite integral

The indefinite integral of \(f\) is the family of all its antiderivatives, written with a constant of integration \(C\).

\[\int x^{n}\,dx=\frac{x^{n+1}}{n+1}+C\quad(n\neq-1)\]
