The video tutorial explains how to find the derivative of a function, evaluate it at a specific point, and derive the equation of the tangent line at that point. The process involves using the power rule for differentiation, substituting values to find the slope, and applying the point-slope form to find the tangent line equation. The tutorial concludes with a graphical verification of the results.
