to find a root for an equation of the form f(x)=0, however you will be starting with ONE guess instead of two.

The first method is called Newton's method or Newton-Raphson and it requires that you calculate the derivative of the function (by hand)

You might want to test your program with the equation ln(sin(x)) = -0.25

Note: make sure you know how to calculate the naperian logarithm in javascript

PLEASE WRITE IN JAVASCRIPT AND WRITE CODE IN NOTEPAD++ OR TEXTEDIT. MAKE SURE TO COPY PASTE YOUR CODE AS WELL.

Note: x needs to be in radians

Note: use an initial approximation of x=1

by the way, you might want to check your answer with a calculator, it should be around

x= 0.8927517423921186
