Show that the relation Rho on R defined as Rho ={(a, b) ;a greater than or equal to b} is reflexive and transitive but not symmetric?
The scalar product of the vectors icap+jcap+kcap with unit vector along the sum of the vectors 2icap+4jcap-5kcap
And lambda icap+ 2jcap+3kcap is equal to1. Find lambda.
