Asked by Alice

Which of the following definite integrals could be used to calculate the total area bounded by the graph of y = sin(x), the x-axis, x = 0, and x = π

a) ∫ from π to 0 sin(x)dx
b) ∫ from π to 0 -sin(x)dx
c) 2∫ from π to 0 sin(x)dx
d) 1/2∫ from π to 0 sin(x)dx
Answered by oobleck
clearly you want ∫ from 0 to π sin(x)dx
But that's not one of the choices.
Now recall that ∫ b to a f(x) dx = -∫ a to b f(x) dx = ∫ a to b -f(x) dx

The teacher gave me only these four choices. :(

Oh come on!
It's (B)
Read what I gave you!
