Question
Find the coordinate matrix of x in Rn relative to the basis B'.B' = {(4, 3, 3), (−11, 0, 11), (0, 9, 2)}, x = (26, 3, −19)[x]B' =
Solution
To find the coordinate matrix of x in Rn relative to the basis B', we need to solve the system of linear equations that results from setting the vector x equal to a linear combination of the basis vectors in B'.
The basis B' is given by B' = {(4, 3, 3), (−11, 0, 11), (0, 9, 2)} and the vector x is given by x = (26, 3, -19).
We can write this system of equations as follows:
4a - 11b = 26 3a + 9c = 3 3a + 11b + 2c = -19
This is a system of three equations in three unknowns (a, b, c), which can be solved using various methods such as substitution, elimination, or matrix methods.
Once we find the values of a, b, and c, these will give us the coordinates of the vector x in the basis B'. These coordinates will form the coordinate matrix [x]B' = (a, b, c).
