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

secant method uses any one of the the finite difference approximations to the derivative.

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

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
