The answer I’m getting from this triple integral says it’s wrong. I got 13/63 and I can’t figure out why it’s wrong. I’m pretty sure that my integration is right, idk if I’m calculating it right though

i cant help this but

#

WHAT THE FUCK

visual schooner
ripe mirage
#

ok so we do first integral

#

do it

visual schooner
#

I did

ripe mirage
#

what you get

visual schooner
#

I got $2x^3+2x^2-2xy$ after integrating with respect to z

#

3/2 * z^3 + zx - zy

#

3/2*x^3 + x^2 -xy - 3/2 * -x^3 + x^2 - xy

#

3 * x^3 + 2x^2 - 2xy

K?

visual schooner
#

$because when you integrate with respect to z, the 3z^2 just becomes z^3, and so it’s then z^3 +xz-yz at the interval [-x ,x]$

ripe mirage
#

no we will use symbo lab

Did you use chat gbt?

#

💀

ripe mirage
#

but then i realized

#

that you are correct

visual schooner
#

I don’t trust any AI technology for mathematics. Obviously it got the wrong answer

ripe mirage
#

because the power rule says

#

sorry

#

but now you have first integral

#

and then you do power rule again and again

ripe mirage
#

to get all the integrals

#

O sorry

rough trout
#

O

visual schooner
#

What did you get then?

#

Braden

rough trout
#

I didn’t solve it yet

#

I don’t have paper

#

Unless this is mental math stuff

#

If you integrate with respext to z dont you get z^3+xz-yz

visual schooner
#

Yea, you then evaluate it at [-x, x]

rough trout
#

How

#

Oh yeah it’s a definite integral

visual schooner

(y^9-y^6) / 6 + 2 * y^7 / 21

ripe mirage
#

i did solve

#

Sorry

ripe mirage
#

@visual schooner what did you get for answer

ripe mirage
visual schooner
#

13/63

ripe mirage
#

wait

#

that feels wrong

#

i forgot to do last integral

#

i think

visual schooner
ripe mirage
#

i got 11 / 21

visual schooner
#

That’s wrong

ripe mirage
#

ok

#

sorry

#

bruh i give up i will ask calculator

visual schooner
#

You integrated wrong

ripe mirage
#

calculator sayed 19/63

#

bruh everyone is wrong???

visual schooner
#

Hold up

#

I’ll try plugging it in again with my answer

#

I got 19/63

ripe mirage
#

i will give you very good suggestion @visual schooner

#

you can use the wolfram alpha calculator

#

to check answer

visual schooner
#

Nah I’m good

normal sphinx
#

i got 1/9+4/21

visual schooner
#

Ill just put it in my answer to see if it is right

visual schooner
normal sphinx
#

which is 19/63

#

yea

visual schooner
#

The triple integral

#

I figured it out

normal sphinx
#

was it 19/63

ripe mirage
visual schooner
#

Yea

normal sphinx
#

👍

ripe mirage
#

it will hepl you check if you gotten correct answer

visual schooner
#

I put the numbers in my calculator wrong
