maths integration problem

[tame obsidian]

Genuinely don’t know how to do 7c😭

integrate the blue bit

then the red bit

and add it up

to integrate it you do area under curve - the line

[flat dew]

ned

[tame obsidian]

But by integrating doesn’t that only find the area of the curve above the x axis

[deft widget]

if you minus the line you get under the curve

im pretty sure

[flat dew]

Do you have the coordinates of d?

like if the y value for d is -3 or something

add 3 to the equation of the curve so all of the shaded part is above the x axis

[flat dew]

And then u can integrate and remove the part under the straight line @tame obsidian

[tame obsidian]

I still don’t get it

[deft widget]

yeahh

what a ned

but then the entire graph would flip over

[flat dew]

Wdym

[deft widget]

when you add 3 to the y coord it means the graph would flip to the positive side

[flat dew]

That’s what i want no

Because i want the area

[deft widget]

oh yeah

oops

how do you even know that

[flat dew]

Wdym

[deft widget]

nvm i forgot you’re a ned

ofc you knew

[flat dew]

Figured it out😂

[flat dew]

The red line doesnt even join where it supposed to but still

[deft widget]

why wouldn’t it make a difference if you flip it to the positive though

you’d still get the same answer # pretty sure

[flat dew]

Yes

[flat dew]

Bc its the same area

Im not transforming the ahape at all

Im just putting it in a more appropriate place to integrate

@tame obsidian this is what i meant

Take away red

[deft widget]

ohh then you remove the tráiganle area

yeah i thought so

[flat dew]

Ofc u did ned

[deft widget]

you might as well be taking the exam instead of me

i’m not even doing that well rn 😭

[flat dew]

Nah man I cant compete with a double mathematician

[deft widget]

true you’re too smart of that
