Numerical methods serve as essential tools for solving both algebraic and transcendental equations that are not easily solvable through traditional analytical approaches. The chapter introduces various methods such as Bisection, Regula Falsi, Newton-Raphson, Secant, and Fixed Point Iteration, detailing their principles, steps, pros, and cons. Selecting the appropriate method depends on factors like the nature of the equation, the required accuracy, and whether the derivative information is available.

Term: Algebraic Equations
Definition: Equations that are formed using algebraic operations, such as π₯3β 4π₯ + 1 = 0.
Term: Transcendental Equations
Definition: Equations that involve transcendental functions, such as π^π₯ = 3π₯ or π₯sin(π₯) = 1.
Term: Bisection Method
Definition: A numerical method that continuously bisects an interval where the function changes sign to locate roots.
Term: NewtonRaphson Method
Definition: An iterative root-finding method that uses tangents to approximate solutions, requiring derivative information.
Term: Fixed Point Iteration
Definition: A method where the equation is rearranged into the form π₯ = π(π₯) to find roots iteratively.
