Read this section to see the connection between derivatives and integrals. Work through practice problems 1-5.
Practice 2: is one antiderivative of so
is another antiderivative of so
No matter which antiderivative of you use, the value of the definite integral
Practice 3: . Since is not continuous on the interval [1.3, 3.4] so we can not use the Fundamental Theorem of Calculus. Instead, we can think of the definite integral as an area (Fig. 20).
