## Homework Statement

Integrate the definite integral ∫sin(x)dx given b = ∏ and a = 0.

## Homework Equations

Fundamental theorem of calculus; definite integral = F(b) - F(a)

## The Attempt at a Solution

The anti-derivative is -cos(x).

F(∏) = -(-1) = 1.

F(0) = 1.

F(b) - F(a) = 0.

Why does the book say the answer is 2 then?
