Question

Find the polar coordinates of p(5,5)

Answer 1

Answer:

(5√2,45)

Step-by-step explanation:

Here, x = 5 and y = 5

.. the point lies in the first quadrant

Let the polar coordinates be (r, 0)

r² = x² + y² = 5² + 52 = 25 + 25 = 50

r = 5√√√2 ...[:r> 0]

tane = = = 1 5

Since the point lies in the first quadrant and

0 ≤ 0 < 2π, tan0 = 1 = tan45°

..0 = 45°

.. the polar coordinates of the given (5√2,45°). point are

Answer 2

Answer:

5√2,45

Step-by-step explanation:

Here, x = 5 and y = 5

.. the point lies in the first quadrant

Let the polar coordinates be (r, 0)

r² = x² + y² = 5² +52 = 25+ 25 = 50

r = 5√√√2 ...[:r> 0]

tane = = =15

Since the point lies in the first quadrant

and

0 ≤ 0 < 2π, tan0 = 1 = tan45°

..0 = 45°

the polar coordinates of the given(5√2,45°). point are
