Question 1 |
For two n-dimensional real vectors P and Q, the operation s(P,Q) is defined as follows:
s(P,Q) = \displaystyle \sum_{i=1}^n (P[i] \cdot Q[i])
Let \mathcal{L} be a set of 10-dimensional non-zero real vectors such that for every pair of distinct vectors P,Q \in \mathcal{L}, s(P,Q)=0. What is the maximum cardinality possible for the set \mathcal{L}?

Thank You Praful Sambhaji Rane,
We have updated the options.
All questions are quite jumbled up and there are questions from probability, algorithms and numerical methods too when it’s supposed to be only Calculus, please update everything accordingl y
