Mathematical equations can be solved in many ways; however some equations cannot be solved algebraically. I am going to show the three methods of solving these types of equations numerically, also I will show each method working, and each method failing.
The three methods are:
* Change Of Sign Method
* Rearranging f(x)= 0 Into The Form x=g(x)
* Newton-Raphson Method
Change of Sign Method
Change of Sign Method Working
I am going to solve the equation f(x) = 0, where f(x) =. The graph of y=f(x) is shown here.
In order to calculate the value of the root in [0.3, 0.4] to 3 decimal places I must check whether the value is closer to 0.309 than 0.310 meaning that the value 0.3095 needs to be calculated. If this value is negative then the root is 0.309 to 3 decimal places however if the value is positive then the root would have to be given as 0.310.
The value of f(x) when x=0.3095 is 0.00614708 meaning that I can deduce that the value of the root in [0, 1] to
