Question:
Use newtons method to approximate the indicated root of the equation correct to six decimal places.

The positive root of sin(x) = x^2

The answer is ...0.876726

Why did they pick this when the obvious root is 0????

Sin(0) = (0)^2 = 0

There are two roots - they want you to find the other one.
The one that it actually helps to use newton's method for.

Yes, they wouldn't ask you to use Newton's Method if they only wanted the trivial root. Try to start with a first approximation that is near the root. I'd try 1.
