    S is one to one but not T
  • b)
    T is one to one but not S
  • c)
    both S and T are one to one 
  • d)
    neither S nor T is one-to-one
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Let the linear transformation S and T :be defined byS(x, y, z) = (2x, ...
We are given that two linear transformations S and T :
R3 --> R3 defined by
S(x, y, z) = (2x, 4x - y, 2x + 3y - z) and T(x, y, z) = (x cos θ - y sin θ, x sin θ - y cos θ, z)
Let (x,y,z) ∈ ker.S
then S(x, y, z) =(0, 0, 0)
Using the definition o f linear transformation, we get
(2x, 4x - y, 2x + 3y - z) = (0, 0, 0) Comparing the components of the co-ordinates, we get
2x = 0
4x - y = 0
2x + 3y - z = 0
On solving these equation for x, y, z, we get
x = 0, y = 0 and z = 0
Hence,ker S = {0, 0, 0}
Thus, S is one-one.
Now, since A is a one-one linear transformation from R3 to R3, which is a finite dimensional vector space therefore S is onto.
Next Let (x, y, z) ∈ ker T
then T(x, y, z) = (0, 0,0)
Using the definition of linear transformation, we get (x cosθ - y sinθ, x sinθ + y cosθ, z) = (0, 0, 0)
Comparing the components of the co-ordinates, we get
x cosθ - y sinθ = 0
x sinθ + y cosθ = 0
z = 0
Now, solving for x, y and z, we get
x = 0 , y = 0 and z = 0
hence, ker T = {0 , 0, 0 }
Therefore, T is one-one
Now, since T is a one-one linear transformation from R3 to R3, which is a finite dimensional vector space therefore T is onto.

Let the linear transformation S and T :be defined byS(x, y, z) = (2x, ...
We are given that two linear transformations S and T :
R3 --> R3 defined by
S(x, y, z) = (2x, 4x - y, 2x + 3y - z) and T(x, y, z) = (x cos θ - y sin θ, x sin θ - y cos θ, z)
Let (x,y,z) ∈ ker.S
then S(x, y, z) =(0, 0, 0)
Using the definition o f linear transformation, we get
(2x, 4x - y, 2x + 3y - z) = (0, 0, 0) Comparing the components of the co-ordinates, we get
2x = 0
4x - y = 0
2x + 3y - z = 0
On solving these equation for x, y, z, we get
x = 0, y = 0 and z = 0
Hence,ker S = {0, 0, 0}
Thus, S is one-one.
Now, since A is a one-one linear transformation from R3 to R3, which is a finite dimensional vector space therefore S is onto.
Next Let (x, y, z) ∈ ker T
then T(x, y, z) = (0, 0,0)
Using the definition of linear transformation, we get (x cosθ - y sinθ, x sinθ + y cosθ, z) = (0, 0, 0)
Comparing the components of the co-ordinates, we get
x cosθ - y sinθ = 0
x sinθ + y cosθ = 0
z = 0
Now, solving for x, y and z, we get
x = 0 , y = 0 and z = 0
hence, ker T = {0 , 0, 0 }
Therefore, T is one-one
Now, since T is a one-one linear transformation from R3 to R3, which is a finite dimensional vector space therefore T is onto.
