Consider the mappingQ. Which of the above are linear transforma...
I. We are given that the transformation T: R3 —> R2 defined by
T (x , y , z) = (x + 1, y + z)
We need to determine the linearity of the given linear transformation.
Now,T'(0, 0, 0) = (1, 0)
Since the image of (0, 0,0) under transformation T is (1, 0) which is not the zero of R2.
Hence, T is non-linear.
II. We are given that the transformation T : R3 --> R defined by
T(x,y,z) = (xy)
We need to determine the linearity of this given transformation.
Since the image of (x, y, z) under linear transformation.
T is an algebraic term of degree 2.
Therefore, T is non linear.
III. We are given that the transformation T: R3 —> R2 defined by
T(x, y, z) = (| x |, 0)
We need to determine the linearity of this linear transformation
Let (1, 0, 0) and (-1, 0, 0) be two vectors of R3
Then T(l,0,0) = (l,0)
andT(-l, 0, 0) = (1, 0)
Now,T [(1, 0, 0) + (-1, 0, 0)] =
T(0, 0, 0) = (0, 0)
and T(1, 0, 0) + T(-1, 0, 0)
= (1, 0) + (1,0) = (2, 0)
Hence, T [(1, 0, 0) + (-1, 0, 0)] ≠ T{ 1, 0, 0) + T (-1, 0, 0).
Therefore, T is non linear.
