Question

find catesiam co orddinate whos polar are. √2. ,pie /4​

Answer 1

Answer:

If Cartesian or rectangular coordinate of a point be (x,y)

and its polar polar coordinate be

(

r

,

θ

)

then

x

=

r

cos

θ

and

y

=

r

sin

θ

here

r

=

2

and

θ

=

π

4

x

=

2

⋅

cos

(

π

4

)

=

2

⋅

y

=

sin

(

π

)

=
