Answer to Question #103610 in Analytic Geometry for aa

Question

If α,β, γ are direction ratios of a line, then so are α^2 ,β^2, γ^2. Is it true or false ?

Answer 1

The statement is false

As the direction ratio of a line can be positive or negative but $\alpha^2 \ ,\beta^2 \ and \ \gamma^2$ will be always positive hence it will not represent the correct direction ratio
