How do you write polar coordinates of (-sqrt 3, 3)?

1 Answer

The polar coodinates : (r, theta)=(2sqrt3, 120^@)

Explanation:

Given: the rectangular coordinates (-sqrt3, 3)

this means x=-sqrt3 and y=3

Convert now to Polar corrdinate system:

Compute r:

r=sqrt(x^2+y^2)=sqrt((-sqrt3)^2+3^2)=sqrt(3+9)=sqrt(12)

r=sqrt(4(3))

r=2sqrt3

Compute the angle theta:

theta=tan^-1(y/x)=tan^-1(3/-sqrt3)=120^@

The polar coodinates : (r, theta)=(2sqrt3, 120^@)
