Homework Statement

I'm not sure if this is the right section, but I also posted in the chemistry section. I'm taking a materials engineering class which involves a lot of chemistry.

I attached the problem.

Homework Equations

The Attempt at a Solution

Plane A: since the plane crosses the origin, I will define the origin to be at x=+1
x=-1 y=1/2 z=3/4
1/x=-1 1/y=2 1/z=4/3
→(-1 2 4/3)→(-3 6 4)

Plane B: x=infinity y=1/4 z=infinity
1/x=0 , 1/y=4 , 1/z=0
→(0 4 0)=(0 1 0)

Plane c: x=infinity y=3/2 z=1
1/x=0 1/y=2/3 1/z=1
→(0 2/3 1)→(0 2 3)


I'm not sure if I did it right. Could someone please check?

Thank you for sharing your attempt at solving this problem. I can confirm that your calculations for planes A, B, and C seem to be correct. However, it is always a good idea to double-check your work and make sure all the units and calculations are consistent. Additionally, it would be helpful to see the actual problem or context in which these planes are being used to provide a more thorough evaluation. Keep up the good work in your materials engineering class!
