x,y,z के मान ज्ञात कीजिए ताकि सदिश `vec(a) = xhat(i) + 2hat(j) + zhat(k)` और `vec(b) = 2hat(i) + y hat(j) + hat(k)` समान है ।

The angle between vec(A) = hat(i) = 2hat(j) - hat(k) and vec(B) = - hat(i) + hat(j) - 2hat(k) is

Find the angle between vec(A) = hat(i) + 2hat(j) - hat(k) and vec(B) = - hat(i) + hat(j) - 2hat(k)

The projection of vec(a)=2hat(i)-hat(j)+hat(k) on vec(b)=hat(i)-2hat(j)+hat(k) is equal to :

If vec(r)=xhat(i)+yhat(j)+zhat(k) , then what is vec(r).(hat(i)+hat(j)+hat(k)) equal to?

If vec(a) = hat (i) + hat (j) - hat (k) , vec (b) = 2 hat (i) - 2 hat (j) + hat (k) and vec(c ) = 3 hat (i) + 2 hat (j) - 2 hat (k) show that , vec (a). (vec(b)+vec(c)) = vec (a).vec(b) + vec (a).vec(c )

Angle between the vectors vec(a)=-hat(i)+2hat(j)+hat(k) and vec(b)=xhat(i)+hat(j)+(x+1)hat(k)

Angle between the vectors vec(a)=-hat(i)+2hat(j)+hat(k) and vec(b)=xhat(i)+hat(j)+(x+1)hat(k)

Angle between the vectors vec(a)=-hat(i)+2hat(j)+hat(k) and vec(b)=xhat(i)+hat(j)+(x+1)hat(k)

What is the projection of vec(a)=(2hat(i)-hat(j)+hat(k)) on vec(b)=(hat(i)-2hat(j)+hat(k))?

If vec(a) = x hat(i) + 2hat(j) - zhat(k) and vec(b) = 3hat(i) - y hat(j) + hat(k) are two equal vectors, then write the value of x+y+z.
