this message is specially for vipin verma which always give incomplete answer vepin verma sir if u dont want to ans queries plz dont answer student query but dont do the formality and tolerating ques as i observe from 5 time u dont want to give proper and complete soln
as earlier when i remind u then u correct soln we r not ur servant that always reposting our queries u r always delaying in answering and which is always in complete
u see in this
expert in exam is the derivation of integration formula can be asked in exam and how can i answer that proof of formula

Let the vector parallel tois n( 3i + k ), and a vector perpendicular to this will be ofthe form.xi+ yj + zk.
Since these two vectors on adding gives us the vector a, we can write the following equations.
x + 3n = 5
y = -2
z+ n = 5
Now, sincevector xi + yj + zk is perpendicular to vector b, their dot product must be zero. Satisfying that condition we get this..
3x + z = 0
z = -3x
and now on sloving the above 3 equations we get
n = 2
x = -1
and z = 3
Therefore the two vectors are obtained in which 6i + 2k is parallel and -i - 2j + 3k is perpendicular to vector b.
The solution obtained can also be checked :
( 6i + 2k) + ( -i - 2j + 3k ) = 5i - 2j + 5k , which is the given vector.
