Answer:

Step-by-step explanation:
The equation of a circle has the following format:

In which r is the radius(half the diameter) and the centre is the point 
Centered at the origin
This means that 
Passing through the point(0,10)
The radius is the distance of any point in which the circle passes to the centre.
Using the formula for the distance between two points.

So

Y = sin x
y' = cos x
y'' = -sin x
y''' = -cos x
y'''' = sin x
Therefore, nth derivative of sin x = sin(nπ/2 + x)
