The point (4, 1) undergoes the following three transformations successively: (a) Reflection about the line y = x (b) Translation through a distance 2 units along the positive direction of the x-axis. (c) Rotation through an angle `pi/4` about the origin in the anti clockwise direction. The final position of the point is given by the co-ordinates.

Explanation

To solve the problem step by step, we will perform the three transformations on the point (4, 1) as described.

### Step 1: Reflection about the line y = x
To reflect a point (x, y) about the line y = x, we swap the coordinates.

For the point (4, 1):
- After reflection:
