Numerical Calculation

Here we want to find sqrt(3)
- This is a number x such that x² - 3 = 0
- That's the x-coordinate of the point where the parabola crosses the x-axis
Make a guess g₁
- Extend the tangent to the parabola at g₁ until it intersects the axis
- This is g₂, which is a better guess than g₁ was
- Repeat as desired
