1. ### Representing polygon at an angle in 3D space with 2D shaded region on its x-y plane?

Re: Representing polygon at an angle in 3D space with 2D shaded region on its x-y pla It's all good, I've already received help on this :)
2. ### Representing polygon at an angle in 3D space with 2D shaded region on its x-y plane?

Re: Representing polygon at an angle in 3D space with 2D shaded region on its x-y pla Thank you so much braintic! I just realised that I already have calculated the vertexes of where the objective function intersects with the constraints as a part of my solution and did what you said and it...
3. ### Representing polygon at an angle in 3D space with 2D shaded region on its x-y plane?

Re: Representing polygon at an angle in 3D space with 2D shaded region on its x-y pla Thanks, I'll definitely give those a go! Also thanks for letting me know I reposted in in the extracurricular section, I thought "Mathematics" meant maths in general haha. -MineTurtle
4. ### Representing polygon at an angle in 3D space with 2D shaded region on its x-y plane?

Hi, I've been working on a Simplex problem and would like to include a 3D graphical check where I graph the objective function (z=9x+7y) along with constraints (e.g. 10a+5b<=5010a+5b<=50, etc.) like this graph or page 2 of this pdf (so that I can visually confirm the solution as the highest...
