Talk:Gauss's method

Definitions of I, J, and K
This may seem like a dumb question, but I don’t see any definition of the symbols $$\mathbf{\hat{I}}$$, $$\mathbf{\hat{J}}$$, and $$\mathbf{\hat{K}}$$. What do they represent?

Looks like they represent the components along three perpendicular axes of a space vector. In other words, where he has for example, a vector:

$$\mathbf{\hat{R}}$$ = (formula 1) $$\mathbf{\hat{I}}$$ + (formula 2)$$\mathbf{\hat{J}}$$ + (formula 3) $$\mathbf{\hat{K}}$$

he means

X component of R = (formula 1)

Y component of R = (formula 2)

Z component of R = (formula 3) — Preceding unsigned comment added by 2001:8003:e422:3c01:990a:5f50:6a54:74fc (talk) 08:05, 20 September 2021 (UTC)
