Develop an Excel spreadsheet to use Newton's method to find the solution of an equation f(x)=3x2+12x11=0 The first derivative of f(x) is: f(x)=6x+12 The formulas of Newton's method are: xn+1=xnf(xn)f(xn) Assume the tolerance value is 0.000001(1106). The spreadsheet should go five iterations, as shown below. The following picture shows the Excel solution. Write the formulas for all cells in the range of A4:F9, in the format of Cell_name = formula: (eg. A5= formula, A4= text_contents)
