Question

Some funky integrals. See attachment.

Answer 1

First one is -6
second one is 6

Answer 2

int [2,6]=int [2,5]+int [5-6]=2+(-8) = -6
the second one is just the negative of the first.

Answer 3

Umm, mind showing me how? :X These practice problems are a bit hard when you have a teacher that doesn't know how to explain.

Answer 4

\[\int\limits_{a}^{b} f(x) dx = \int\limits_{0}^{b}f(x) dx + \int\limits_{a}^{0}f(x) dx\]

where a<0<b

Answer 5

you can replace 0 with c.

c can be any value between a and b

Answer 6

Hmm, okay... I see.
