The Cartesian coordinates of point having polar coordinates`(-2, (2pi)/3)`will be
A
`(1,sqrt(3))`
B
`(sqrt(3),1)`
C
`(1,-sqrt(3))`
D
`(-1,sqrt(3))`
Text Solution
Verified by Experts
The correct Answer is:
C
`(-2,(2pi)/(3))` `x = r cos theta` and `y = r sin theta` `:. x =(-2) cos.(2pi)/(3)` and `y = (-2) sin.(2pi)/(3)` `:. x =(-2) (-(1)/(2))` and `y =(-2) ((sqrt(3))/(2))` `:. (1,-sqrt(3))`
