Question

find the polar co - ordinates of points whose cartesian co - ordinates are (1) (1, √3) (2) (-1, -1)​

Answer 1

Step-by-step explanation:

In the question, rectangular coordinates are given. For given rectangular coordinates

(

x

,

y

)

, the corresponding polar coordinates are

(

r

,

θ

)

We have that

x

and

y

are both positive therefore the point is in first quadrant.

For polar coordinates, we have

x

=

r

cos

θ

y

=

r

sin

θ
