if the position vectors of A,B,C are respectively 2i-j+k,i-3j-5k,3i-4j-4k then cos^2A is
Question
Solution 1
To find cos^2A, we need to find the angle A first.
The position vector of A is given as 2i - j + k.
To find the magnitude of vector A, we can use the formula |A| = sqrt(Ax^2 + Ay^2 + Az^2), where Ax, Ay, and Az are the components of vector A.
In this case, Ax = 2, Ay = -1, and Az = 1.
