Key Concepts

  • Fundamental Theorem of Calculus, Part 1: 

If $f(x)$ is a continuous function over an interval  $[a, b]$,  and the function $F(x)$ is defined by 

$F(x)=\displaystyle\int_a^x f(x) dx$,    then     $F'(x)=f(x)$.   

  • Fundamental Theorem of Calculus, Part 2:

If $f(x)$ is a continuous function over an interval  $[a, b]$,   and $F(x)$ is any antiderivative of $f(x)$,  then 

$\displaystyle\int_a^b f(x) dx=F(b)-F(a)$.
