Literally what the fuck does any of this mean it isn’t even covered by my class why is it on my homework

# Venting Thread (Don't break the rules tho, keep it civil and shit this isn't a place to be all like "hey this guy on the forums really pisses me off" it should be about other shit)

No

We aren’t being tested on this at all

Reading the homework is the first I’ve heard of any of this and likely the last

We’ve had some oddball shit on our homework before but this takes the cake

It’s not even related to what we’re doing in class at all as far as I can tell

it is not black magic fuckery

it is actually *white* magic fuckery

but obviously you couldn’t understand it because of log (6) x = -2

Are you allowed to use computer programs and the like or does it have to be done by hand?

Okay I have no idea what level you are at, but for a) If you solve the system of linear equations using the provided point transformations you end up with the transformation matrix as:

(x1, x2, x3)

(x4, x5, x6)

(x7, x8, x9)

being

(0, 0.5, 0.5)

(0.5, 0.5, 2)

(0, 0, 3)

If that is difficult see this for a simple two dimensional example: https://www.youtube.com/watch?v=JSvygzoV1kg

Putting this in makes the points of the convex hull after the transformation:

(1, 2, 3)

(1, 0, 0)

(0, 1, 0)

(0, 0, 0)

(1, -1, 0) This point being new found from original point (0, 2, 0)

Use this for quick matrix multiplication: https://matrix.reshish.com/multCalculation.php

You can visualize these points in: https://technology.cpm.org/general/3dgraph/

It’s quite easy to see and calculate the area of the faces from that and use them in this formula found here:

I think that should solve a and b is just a more extensive version of it.

Just use Matlab then: http://www.mathworks.com/help/matlab/ref/convhull.html if you have access to it. It’s just multiplying the input points with the transformation matrix and then inputting the transformed points into this matlab function.

It’s A LOT of annoying work by hand, but if you can use a computer it should be done relatively quickly.
