ker:

this is how we solve a question without any parameter in the matrix:

we take each line make and equation out of it and put =0 in the end of each line

than we find the solution to this matrix

(we find the value for X value for Y value for Z of course there might be more than one vector)

and the solution represents the vectors of the ker

i asked previosly what should i do in case of parameters

the answer that i got was

"find the values of parameters for which the rows will be all zeros"

why arent we solving it??????

regarding the Im:

we put =b1 =b2 =b3 in the end of each line

and solve

i dont know how

i got here a simple parameter matrix can u please write the full solution

of maximal value of dim(ker A) and the maximal value of dim(Im A)

i simplified the matrix from the original form to the simplest form

i heard many version many explanations to this sort of problem

can you write an answer to this ????
