5.3 Integration & Anti-derivatives
The Fundamental Theorem of Calculus
Question #3 (Medium): Evaluating the Definite Integral
Based on the Fundamental Theorem of Calculus Part 2, evaluating the definite integral becomes much
easier:∫ ( ) ( ) ( ) where ( ) is the anti-derivative of ( ).
Substituting the beginning and the end points of the interval into the anti-derivative function ( )
evaluates the definite integral.
When trigonometric functions are involved, usually the interval is given as special angles in radian
measure so that the co
