This video tutorial explains how to find the equation of a tangent line at a specific point on a function. It begins by identifying the point of tangency, which involves evaluating the function at the given x-coordinate. Next, the slope of the tangent line is determined by calculating the derivative of the function and evaluating it at the same x-coordinate. With the point and slope known, the point-slope form is used to derive the equation of the tangent line. The tutorial concludes with a graphical verification of the solution.
