The polar form of (-1,√3) is(___,___)

Mathematics
1 answer:
Klio2033 [76]3 years ago
4 0

Answer:

(2, 2/3 * pi)

Step-by-step explanation:

( -1, sqrt(3))

to find the radius

sqrt(x^2 + y^2) = r

sqrt( (-1)^2 + (sqrt3)^2) = r

sqrt(1+3) =r

sqrt(4) =r

2=r


to find theta

theta = arctan (sqrt(3)/-1)

theta = -60 degrees

you need theta between 90 and 180

add 180 to theta

theta = 120


you need theta in radians

120 * pi/180 = 2/3 * pi
