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
integrate ex(logsinx+ cosx)dx limit from pie by 4 to pie by 2

Yes integrate using limits can be asked in the examination.Just go through the NCERT examples and solve the limit sum exercise.

2- u see here this is alsoincomplete
express vector a vector = 5i-2j+5k as sum of 2 vectors such that 1 is parallel to vector b and and other is perpendicular to vector b where b = 3i+k
the scaler pdt of the vector i+j+k with a unit vector along the sum of vectors 2i+4j-5k and lambda i +2j +3k is equal to 1 find the lambda

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
y = -2
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.
