perp
Denotes perpendicularity between geometric objects, particularly lines, planes, or vectors in mathematics.
Overview
Essential in geometry, linear algebra, and vector analysis for expressing spatial relationships between mathematical objects.
- Commonly used in geometric proofs to indicate lines or planes meeting at right angles
- Appears frequently in vector space theory to denote orthogonal vectors
- Important in physics and engineering when describing perpendicular forces or structural components
- Used in coordinate geometry to specify perpendicular lines with slopes that are negative reciprocals
Examples
Denoting perpendicular lines in geometry
\text{Line } l_1 \perp l_2
Expressing orthogonal vectors in linear algebra
\vec{u} \perp \vec{v} \implies \vec{u} \cdot \vec{v} = 0
Indicating independent events in probability theory
P(A \perp B) = P(A) \cdot P(B)
