Hi, in this question, given that t1 r2 to r2 equals t1 of x ,y equals x -3y ,3x plus 5y and t2 of x ,y equals y ,0.
00:26
We have to evaluate a and a'.
00:29
So, here first we can write it as t of x ,y equals t2 composite t1 of x ,y which is equal to t2 of t1 of x ,y which is equal to t2 of t1 of x ,y is nothing but x -3y ,3x plus 5y and here t2 of x ,y is nothing but y ,0.
00:56
So, y is 3x plus 5y ,0.
01:01
Therefore, which is the required t of x ,y.
01:05
Next t of x ,y can be written as 3x plus 5y ,0.
01:13
We know that the standard basis e1 vector equals 1 ,0 and e2 vector equals 0 ,1 and here t is the r2 to r2 be the transformation.
01:34
So, the domain of t is r2.
01:41
To find the columns of the standard matrix for the transformation, we will need to find t of e1 vector and t of e2 vector.
01:53
So, we can write it as t of e1 vector equals t of 1 ,0 which can be written as 1 can be written as 3 into 1 plus 5 into 0 and here 0.
02:11
So, which can be written as 3 ,0.
02:15
Next t of e2 vector which is equal to t0 ,1 which is equal to 3 into 0 plus 5 into 1 and here 0.
02:28
So, we can write it as 5 ,0...
