If `5u + 3v = 13uv and u -v = uv`, then `(u, v) =` _____

If u+v = 84 and u-v = 4 then u:v is equal to: यदि u+v = 84 तथा u-v = 4 है, तो u: v का मान होगा :

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

If |u|=|v|=1uv!=-1 and z=(u-v)/(1+uv) then (a) |z|=1( b) Re(z)=0 (c) Im(z)=0 (d) Re(z)=Im(z)

Solve : 3( 2u +v) = 7uv 3(u + 3v) = 11 uv
