Exercise · ZW-INDEFINITE-INTEGRAL-007 · ★★☆ Intermediate
Compute \(\int e^{2x}\,dx\).
Choose one option.
Show answer
- B. \(\frac{e^{2x}}{2}+C\)
Explanation
Since \(\frac{d}{dx}e^{2x}=2e^{2x}\), we divide by 2: the antiderivative is \(\frac{e^{2x}}{2}\).
Review the concept: Indefinite integral
The indefinite integral of \(f\) is the family of all its antiderivatives, written with a constant of integration \(C\).
\[\int x^{n}\,dx=\frac{x^{n+1}}{n+1}+C\quad(n\neq-1)\]
