Question

If the polar coordinates of the point (x, y) are (r,
),
determine the polar coordinates for the points
(a) (x, y), (b) (2x, 2y), and (c) (3x, 3y).

Answer 1

Vectors aate hain?

Answer 2

Haan par phir bhi problems nahi Bante

Answer 3

The vectors \(\langle x,y\rangle , ~\langle 2x,2y\rangle , ~ \langle 3x,3y\rangle\) point to the same direction and thus have the same angle from origin.

Answer 4

How ?

Answer 5

I can draw them for you.

Answer 6

Ab aaya samajh mein?

Answer 7

So \(\theta\) will remain the same. Only the \(r\) will change.
