If origin is the centre of a circle with radius 17 units, find the coordinates of any four points on the circle which are not on the axes. (Use the

Pythagorean triplets)


The co-ordinates can be represented as (17cos(Ф),17sin(Ф))
where Ф ∈ [0,2π]
so for any four points
take Ф=30,45,60 and 75
so the co-ordinates are (17√3/2,17/2) (17/√2,17/√2)  (17/2,17√3/2) and  (4.4,16.42)
