Answer:
The points form a equilateral triangle of side 5.78 units.
Step-by-step explanation:
The length of the sides of the triangle is calculated using the distance formula.
The distance between the points (x₁,y₁) and (x₂,y₂) is
Now,
AB =
BC =
CA =
The length of the sides of the triangle is 5.78. All the sides are equal in length. It is an equilateral triangle.
Assuming the function is 
, and not 
which would be its own Maclaurin polynomial right away.
Recall the geometric power series,
where
