Show that if `vecu.(dvecu)/(dt)=0` the vector `vecu` is of constant magnitude.

Prove that [ vecu vecv vecw ] + [ vecu vecw vecv] =0 .

Let vecu, vecv and vecw be such that |vecu|=1,|vecv|=2 and |vecw|=3 if the projection of vecv " along " vecu is equal to that of vecw along vecu and vectors vecv and vecw are perpendicular to each other then |vecu-vecv + vecw| equals

Let vecu, vecv and vecw be such that |vecu|=1,|vecv|=2 and |vecw|=3 if the projection of vecv " along "h vecu is equal to that of vecw along vecu and vectors vecv and vecw are perpendicular to each other then |vecu-vecv + vecw| equals

Let vecu and vecv be unit vectors such that vecu xx vecv + vecu = vecw and vecw xx vecu = vecv . Find the value of [vecu vecv vecw ]

Let vecu and vecv be unit vectors such that vecu xx vecv + vecu = vecw and vecw xx vecu = vecv . Find the value of [vecu vecv vecw ]

Let a,b,c denote the lengths of the sides of a triangle such that ( a-b) vecu + ( b-c) vecv + ( c-a) (vecu xx vecv) = vec0 For any two non-collinear vectors vecu and vecu ,then the triangle is

Let a,b,c denote the lengths of the sides of a triangle such that ( a-b) vecu + ( b-c) vecv + ( c-a) (vecu xx vecv) = vec0 For any two non-collinear vectors vecu and vecu ,then the triangle is

If vecu and vecv be unit vectors. If vecw is a vector such that vecw+(vecwxxvecu)=vecv then vecu.(vecvxxvecw) will be equal to
