Exercise · ZW-FUNDAMENTAL-THEOREM-OF-CALCULUS-004 · ★☆☆ Basic
Compute \(\displaystyle\int_{0}^{\pi} \sin {x}\,dx\).
Choose one option.
Show answer
- A. \(2\)
Explanation
An antiderivative is \(F(x)=- \cos {x}\). By the fundamental theorem, the integral is \(F(\pi)-F(0)=2\).
Review the concept: Fundamental theorem of calculus
It links derivatives and integrals: a definite integral equals an antiderivative evaluated at the endpoints, and differentiating an integral with variable upper limit returns the integrand.
\[\begin{gathered}\int_a^b f(x)\,dx=F(b)-F(a)\\ \frac{d}{dx}\int_a^x f(t)\,dt=f(x)\end{gathered}\]
