 - **Trial and Error:** this method adds or subtracts until it reaches the solution(s).
 - **Bisection**: this method involves repeatedly bisecting the interval in which the solution resides.
-- **Regula Falsi:** this method approximates the solution(s) by linear interpolation between the values of the function at the endpoints of an interval.
+- **Iterations:** this method approximates the solution(s) by linear interpolation between the values of the function at the endpoints of an interval.
 - **Newton-Raphson:** This method approximates the solution(s) by using the function and its derivative to iteratively improve an initial guess.
 - **Secant:** this method approximates the solution(s) by using a line that passes through two points on the graph of the function.
 - **Steffensen:** this method approximates the solution(s) by using a fixed point iteration method with an additional acceleration step using the function's second derivative.
