Trial and Improvement Method for Approximating Solutions of Equations

The video tutorial explains the trial and improvement method for solving equations, particularly when exact solutions are difficult to find. It covers both graphical and algebraic approaches, demonstrating how to narrow down the solution range to achieve desired accuracy. An example problem is provided to illustrate the process in detail.
