The positive root of 
Equate to 0

So, we have our function to be:

Differentiate the above function:

Using Newton's method of approximation, we have:

Plot the graph of
to get
--- see attachment for graph
From the attached graph, the first value of x is at 2.2; so:

So, we have:



The process will be repeated until the digit in the 6th decimal place remains unchanged



Hence:
Answer:
we have centre of circle as (30,40) and radius = 1
Step-by-step explanation:
Given that a car is moving on a circle on a plane.
At time t (seconds),

and


when we square and add both the equations we get

(since sin square + cos square = 1 always)
i.e. we have centre of circle as (30,40) and radius = 1
