Find the angle between two vectors `vecp` and `vecq` are 4,3 with respectively and when `vecp.vecq`=5`.

What can be the angle between vecP+vecQ and vecP-vecQ ?

If vecP -vecQ - vecR=0 and the magnitudes of vecP, vecQ and vecR are 5 , 4 and 3 units respectively, the angle between vecP and vecR is

If vecP.vecQ=PQ then angle between vecP and vecQ is

If vecP.vecQ=PQ then angle between vecP and vecQ is

If vecP.vecQ=PQ then angle between vecP and vecQ is

For any two vectors vecp and vecq , show that |vecp.vecq| le|vecp||vecq| .

For any two vectors vecp and vecq , show that |vecp.vecq| le|vecp||vecq| .

If vecp,vecq and vecr are perpendicular to vecq + vecr , vec r + vecp and vecp + vecq respectively and if |vecp +vecq| = 6, |vecq + vecr| = 4sqrt3 and |vecr +vecp| = 4 then |vecp + vecq + vecr| is
