Newtons method question

[domo256]

Find the positive value of X which satisfies X= 1.200 sin (x). Give the answer to four places of accuracy. Remember to calculate the trig functions in radian mode.

I normally show my work but I dont even know where to start.. it looks simple enough... any help would be appreciated..

Have you been assigned the use of Newton's Method?

Writing it down would be a good place to start, no?

That normally would be: \(\displaystyle x_{n+1}=x_{n}-\frac{f(x_{n})}{f'(x_{n})}\)

Your only real task is to determine 'f'. Might I suggest f(x) = x - 1.200*sin(x)?

Careful where you start. You may find any of the three solutions.
