Question

what are the coordinates of the terminal point corresponding to θ=15pi/6

Answer 1

coordinates in x-y or in r-θ ?

Answer 2

its based on the unit circle

Answer 3

15/6=2.5

so 15/6 π = 2.5 π = 0.5 π =π/2

the point can be represented as

(r, θ) = (1, π/2)

Answer 4

if you with to represent in x-y

use r =√(x^2+y^2)
θ = atan2 (y, x)

Answer 5

thank you so much, i really appreciate it
