I wants to implement newton raphson method to estimate two unknown variables C and theta from equation in matlab.

x0 = xf + C*sin(xf+theta)

Can any explain the steps involving this estimation.

Is there any other method which can be used other than newton raphson method.

C=(x0-xf)/sin(xf+theta)
and
theta=arcsin{(x0-xf)/C}-xf

So you assign two initial value for these variables then find them by inserting the value that you have already found in the equation before.
It should normally work if it converges.
