Question

can someone please help with this question? TRAPEZIUM RULE!!

would attach the file below....

Answer 1

Here is a drawing of the situation.

Answer 2

@ZeHanz ur doing it the way i would:D

Answer 3

But my way is a lot confuser... lol

Answer 4

OK, so we're on the eight track!

You have to calculate the area of two trapeziums. Both have width pi/8.
You also need the different heights:
I defined \(f(x)=\dfrac{1}{1+\tan x}\), then you need:

\(f(0) = 1\),
\(f(\frac{\pi}{8}) \approx 0.707\),
\(f(\frac{\pi}{4}) = \frac{1}{2}\).

Do you know how to calculate the area of a trapezium?

Answer 5

Or do you call the things trapezoids? (sound like some aliens to me :)

Answer 6

LOL.....yh i know how to calculate the area of trapezoids..

Answer 7

OK, so you're good now? (I got 0.57 as an answer)

Answer 8

@LizzyLove<3: I ALWAYS make a drawing (in Geogebra) to see what's going on.
It really helps!

Answer 9

thanks alot! what you got is correct when i checked the answer booklet

Answer 10

@ZeHanz ME TOO!! well i draw for everything, in all my classes, it really helps me the most in geometry or just math:D Im a visual learner:D
