SOLUTION: Q:1- What is the rank of unit matrix of order n? Q:2- If S is linear and onto transformation from R^3 to R^3 while T is linear and one-one transformation from R^3 to R^3 then S

Question 1194925: Q:1- What is the rank of unit matrix of order n?
Q:2- If S is linear and onto transformation from R^3 to R^3 while T is linear and one-one transformation from R^3 to R^3 then S and T preserves what?
Q:3- If T is kernel from R^3 to R^3 then T(x, y, z) = (x, y, 0) is plane or space? Justify your answer.
Note: Here R^3 means three dimension space.

Question 2 is mathematically non-sensical.

Question 3 is mathematically non-sensical and is written in illiterate way.

Having two questions in the post, written in illiterate way,
I do not find possible for myself to answer third question.

If in the future I will see similar posts, written in illiterate way,
I will collect the links to these posts and will write to the managers
of this project asking them to REMOVE from the project those who submit this nonsense.
