Yes, exactly. But you can adjust the axes of the graph to get an 1:1 display (ie. x is -10..10 and y is -5..5, not a square space). And that is the default in the TI graphs IIRC.
So as long as you set up the projection to match the screen resolution aspect ratio, you'll get perpendicular lines correctly.
- vardump 11y agoAt least on TI-85, I think the pixels are slightly taller than wide, by about 20%. Not square shaped. I'd assume same is true for other TI-8x calculators.
- thaumasiotes 11y agoAs discussed in the other comments, the default window is -10..10 and -10..10 in 3:2 aspect ratio.
