Here's the question you clicked on:

what are the coordinates of the terminal point corresponding to θ=15pi/6
coordinates in x-y or in r-θ ?
its based on the unit circle
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)
if you with to represent in x-y use r =√(x^2+y^2) θ = atan2 (y, x)
thank you so much, i really appreciate it
