The document describes the bisection method, a root-finding algorithm that uses binary search to find roots (values that make a function equal to zero) of a continuous function. It works by repeatedly bisecting an interval known to contain a root and narrowing in on the root. The key steps are: (1) Start with an interval [a,b] where the function changes sign, ensuring a root exists in the interval. (2) Calculate the midpoint m of the interval. (3) Determine which subinterval [a,m] or [m,b] contains the root based on the sign change and update the interval accordingly. (4) Repeat until the interval size is small enough to approximate the root.
This document describes the False Position Method for finding the roots of equations. The method uses linear interpolation to estimate the root between two initial guesses that bracket it. It improves on the bisection method by choosing a "false position" where the line between the guesses crosses the x-axis, rather than the midpoint. The false position formula is derived using similar triangles. An example applying the method to find a root of x^3 - 2x - 3 = 0 is shown. The merits of the false position method are faster convergence compared to bisection, while the demirits are possible non-monotonic convergence and lack of precision guarantee.

The False-Position Method is an iterative root-finding algorithm that improves upon the bisection method. It uses the slope of a line between two points to estimate a new root, rather than always bisecting the interval. Given an initial interval where the function changes sign, it calculates a new x-value at the intersection of the x-axis and a line through two existing points. It then chooses a new interval based on where the function changes sign again. The method is similar to bisection but uses a different formula to calculate the new estimate. An example finds a root of 3x + sin(x) - exp(x) = 0 between 0 and 0.5, converging to a solution of approximately 0.

Repeating this process iteratively refines the approximation until the root is found to within a desired precision. The secant method converges faster than bisection near roots and does not require evaluating derivatives, but it may fail to converge for some functions.

The secant method is a root-finding algorithm that uses successive secant lines to converge on a root of an equation. It begins with two initial points and finds where the secant line between those points intersects the x-axis. It then uses the intersection point as the next estimate and draws a new secant line. This process repeats until the estimate converges within a specified tolerance of the root. The secant method requires only function evaluations, unlike other methods that also require derivative evaluations. However, it may not always converge and provides no error bounds for the estimates.
- A function is a rule that maps each input to a unique output. Not every rule defines a valid function.
- For a rule to be a valid function, it must map each input to only one output. The domain is the set of valid inputs, and the range is the set of corresponding outputs.
- Functions can be represented graphically by plotting the input-output pairs. The graph of a valid function should only intersect the vertical line above each input once.
The document summarizes the solution to finding the infinite square root of 1 - 17/16. It shows that this expression equals either 1/2 or approximately 0.073. Graphing the function f(x) = 1 - 17/16 - x reveals that starting at 1, iterations of f(x) will converge to 1/2, not 0.073, since 1/2 is a stable fixed point while 0.073 is unstable. Therefore, the infinite square root equals 1/2.

2) Substituting into the formula xn+1 = xn - f(xn)/f'(xn)
3) Differentiating to find f'(x) and iterating the formula using a calculator until convergence
The method may fail if the starting value is near a stationary point where f'(x) = 0, causing division by zero in the formula.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

2. Bisection Method Working Rule
•It begins with two values for x that bracket a root. It determines that they do in fact
bracket a root because the function f(x) changes signs at these two x-values and, if f(x) is
continuous.
•The bisection method then successively divides the initial interval in half, finds in which
half the root(s) must lie, and repeats with the endpoints of the smaller interval
•Suppose, we wish to locate the root of an equation f (x) = 0 in an interval, say (x0, x1). Let
f (x0) and f (x1) are of opposite signs, such that f (x0) f (x1) < 0.
4. Formula Derivation
𝑥2=
𝑥0 + 𝑥1
2
If f (x2) = 0, then x2 is the desired root of f (x) = 0.
However, if f (x2) ≠ 0 then the root may be between x0 and x2 or x2 and x1.
• As we know f(𝑥0)> 0 then, we can find which value to replace for next iteration by the
following condition such as
• If f(𝑥0)*f(𝑥2) < 0 then, 𝑥1= 𝑥2 else 𝑥0= 𝑥2
General form of this method is given by:
𝑥𝑛 =
𝑥𝑛−2 + 𝑥𝑛−1
2
6. MERITS OF BISECTION METHOD
1. The iteration using bisection method always produces a root, since the method brackets
the root between two values.
2. As iterations are conducted, the length of the interval gets halved. So one can guarantee
the convergence in case of the solution of the equation.
3. Bisection method is simple to program in a computer.
7. DEMERITS OF BISECTION
METHOD
1. The convergence of bisection method is slow as it is simply based on halving the
interval.
2. Cannot be applied over an interval where there is discontinuity.
3. Cannot be applied over an interval where the function takes always value of the same
sign.
4. Method fails to determine complex roots (give only real roots)
5. If one of the initial guesses “𝑎0” or “𝑏0” is closer to the exact solution, it will take
larger number of iterations to reach the root.
9. Example Numerical

As f(1.187500)= 0.237061
i.e. F(1.187500)>0
𝑥5 =
