If `veca=xveci-yvecj` and `vecb=yveci+xvecj`, `|vecaxxvecb|=5`then locus of `(a,b)` is

If |veca|=13,|vecb|=5 and veca.vecb = 60 then |vecaxxvecb| is

If |veca|=5,|vecb|=8 and veca.vecb=24 , then find |vecaxxvecb|

Find veca.vecb if |veca|2, |vecb|=5,a and |vecaxxvecb|=8

If |veca|=8,|vecb|=3 and |vecaxxvecb|=12 , then value of veca*vecb is :

If |veca|=13,|vecb|=5 and veca*vecb=60 , then find |vecaxxvecb| .

Find veca.vecb if |veca|=2, |vecb|=5,and |vecaxxvecb|=8

Let veca =veci -veck, vecb = xveci+ vecj + (1-x)veck and vecc =y veci +xvecj + (1+x -y)veck . Then veca, vecb and vecc are non-coplanar for
