if the line is y=mx+b
and I want the integral from f to g (on the x axis), and f < g

[math]\left. \left( \frac{m}{2}x^{2} + bx \right) \right|^{g}_{f}[/math]

why isn't there a ∫
?

Does any one of you guys have that pic with recommended books from basic maths to advanced stuff?
I usually see it a lot around Veeky Forums, but now that I want it I can't find it.
Thanks in advance!

The rules of integration is the same for any curve. Try it out:
>Integrate a line like y = 2x in an interval like 0 to 4
Then compare the results with
>The area calculated with the triangle area formula

Then, I'd suggest you how to get to the integration rules by using its definition, that is, try to understand how the idea of the integral's been developed. Don't just memorize things.
Good luck!

It's a fucking meme, just go to the Veeky Forums wiki, it's linked in the sticky. If you want more help, go to /mg/ and ask concrete questions, but the wiki books are pretty good, so I recommend you pick a textbook and stick to it rather and trying to find THE textbook, because you won't.

did anyone here have math anxiety at some point?
the idea of entering my calc class and flopping over the material gives me such a tiresome headache.
i want to master it though.

Thanks!
Actually, it's for a friend of mine. He's trying to learn basic maths and I don't really know what to suggest him and I can't suggest him the books that I'm used to because he won't understand a thing.
I'll take a look at the wiki then!

You mean, like bored?

I've already integrated. [math]\int_{f}^{g} (mx+b)dx[/math] is precisely what I have there
