The complex numbers u, v and w are related by `(1)/(u) = (1)/(v) + (1)/(w)`. If v = 3 -4i and w = 4 + 3i , find u in rectangular form.

Let u,v and w be vectors such that u + v + w = 0. If |u| = 3, |v| = 4 and |w| = 5, then uv.vw.wu is equal to

The component forms of vectors u and v are given by u = u = (:5,3:) and v = (:2,-7:) . Given that 2u + (-3v) + w = 0 , what is the component form of w?

If z_(1),z_(2),z_(3) and u,v,w are complex numbers represending the vertices of two triangles such that z_(3)=(1-t)z_(1)+tz_(2) and w = (1 -u) u +tv , where t is a complex number, then the two triangles

If z_(1),z_(2),z_(3) and u,v,w are complex numbers represending the vertices of two triangles such that z_(3)=(1-t)z_(1)+tz_(2) and w = (1 -u) u +tv , where t is a complex number, then the two triangles

Let vec u , vec v and vec w be vector such vec u+ vec v+ vec w= vec0 . If | vec u|=3,| vec v|=4 and | vec w|=5, then find vec u . vec v+ vec v . vec w+ vec w . vec u .
