Explanation:
We have the coordinate
Coordinates in polar form have the standard form
To convert from polar form to Cartesian form, we use the following formulas:
#color(red)(x) = color(green)(r)coscolor(purple)(Θ)# #color(blue)(y) = color(green)(r)sincolor(purple)(Θ)#
Now, let's plug stuff in. We know
We get
Explanation:
Cartesian coordinates
hence the cartesian coordinates of given point are
