Express the given vector `vec(A)` (shown graphically ) in unit vector notation.

Express the vector in unit - vector notation.

If P(-1,2) and Q(3,-7) are two points, express the vectors vec(PQ) in terms of unit vectors hatiand hatj . Also find the distance between points P and Q. What is the unit vector in the direction of vec(PQ) ? Verify that magnitude of unit vector indeed unity.

If vec(a) be a unit vector, then :-

Expressing A Vector In Unit Vector Notation

If the incident ray on a surface is along the unit vector vec v , the reflected ray is along the unit vector vec w and the normal is along the unit vector vec a outwards, express vec w in terms of vec a and vec v

If the incident ray on a surface is along the unit vector vec v ,the reflected ray is along the unit vector vec w and the normal is along the unit vector vec a outwards,express vec w in terms of vec a and vec v

If the incident ray on a surface is along the unit vector vec v , the reflected ray is along the unit vector vec w and the normal is along the unit vector vec a outwards, express vec w in terms of vec a and vec v

If the incident ray on a surface is along the unit vector vec v , the reflected ray is along the unit vector vec w and the normal is along the unit vector vec a outwards, express vec w in terms of vec a and vec v
