Rajasthan Board RBSE Class 12 Maths Chapter 13 Vector Ex 13.3
Find vector product of vectors
Find perpendicular unit vector of vectors
For vectors and , prove that
According to question,
If , , are unit vectors, such that
. = 0 = . and angle between and is , then prove that = ± 2 ( × )
Find the value of
We know that if and are two vectors and θ is the angle between them, then
Find vector perpendicular to the vectors
whose magnitude is 9 unit.
also, explain geometrically.
= 2(vector area of parallelogram ABCD).
Thus we conclude that area of parallelogram whose adjacent sides are diagonals of given parallelogram is twice the area of given parallellogram.
For any vector , prove that
If two adjacent sides of a triangle are represented by vectors
then find the area of triangle.
