Answer
True
Work Step by Step
Fundamental theorem of Calculus states that for a continuous function $f$ on the interval $[a,b]$ and for any antiderivative of $f$, say $F$, $\int_a^bf(x)dx=F(b)-F(a)=F(x)|_a^b.$
$\int_a^bf(x)dx$ is the definite integral and $F(x)$ is the antiderivative of $f(x)$. Clearly, the theorem demonstrates a relationship between the both, i.e. the definite integral and an antiderivative of the function. Hence it is true.
