Answer 5

I found it on the first one you sent me. Did you graph this to see what it looked like?

Answer 6

Let me guess....no

Answer 7

no not at all

Answer 8

Okay, well let me graph it for you and send it to you

Answer 9

I am lazy

Answer 10

Hey u r so nice

Answer 11

but lie it is so annoying since it 1 2 3 and 4. i wld like it to be in radians

Answer 12

3 is like pi

Answer 13

I am supossed to be heading to bed in 3 minutes LOL

Answer 14

Just a sec

Answer 15

ok

Answer 16

That should give you a better idea of what is going on

Answer 17

ya ok i saw it

Answer 18

my answer though may be correct

Answer 19

It must be since i used my calc

Answer 20

Basically, when you take the integral you should get a positive value. You have two areas

One area goes from 0 to 2.5
the other goes from 2.5 to 4

The area above the x-axis from 0 to 2.5 is greater than the area below the x-axis from 2.5 to 4

Therefore, the total area when added won't be that much. because you're subtracting one area from the other area.

Answer 21

so i got s/t like .8048960342

Answer 22

no

Answer 23

3.99 or approx 4

Answer 24

y not?

Answer 25

Because I will show you

Answer 26

Y show me :D

Answer 27

oops, nevermind

Answer 28

so am i correct?

Answer 29

and what does it mean to interpret in in erms of area??
I dont get that

Answer 30

Hero is here but not here at the same time

Answer 31

Yes, you're right. It's only .804

Answer 32

ok so what does it mean to interpret it in terms of area?

Answer 33

It means to measure the space between the x axis and the curve

Answer 34

I wish you had my calculator. That way you could see visually how it works

Answer 35

oh so the answer wld be this .804??

Answer 36

christmas i will find a good deal hopefully. My dad is already going bankrupt from me!!!

Answer 37

HERO where r u?

Answer 38

I will show you how to make sense of this.

Answer 39

I'm going to send you another picture

Answer 40

ok. It isnt area but just displacement no??

Answer 41

oh ya thanks :D

Answer 42

I'll show you exactly what it is. It' will be almost dummy proof

Answer 43

:D:D:D

Answer 44

Thanks

Answer 45

U r the best

Answer 46

x = 2.5 is where the function hits the x axis and also where y = 0
Take the integral of the function from 0 to 2.5
Then take the integral of the function from 2.5 to 4

The absolute value of their differences will be the total area under the curve of the function from 0 to 4

Answer 47

Does it make any sense yet?

Answer 48

so basically it is the change in placement

Answer 49

I hope i am not stressing you out but like it is the positive area minus the negative area which is change in placenent kind of

Answer 50

The area under the curve is essentially the combined area of the space under the curve that you see shaded in grey. Yes, it does INVOLVE subtracting the areas below the x-axis from those above the x-axis. But area simply means "region of space". I think that's what you should understand about it. You have a region of space under the curve of a function and that is what you are measuring.
