Learn to find the tangent line through the point of the function

The video tutorial explains how to find the tangent line to a curve at a given point, even if the point is not on the graph. It covers the use of derivatives to determine the slope of the tangent line and the process of solving for the equation of the tangent line. The tutorial also includes a graphical interpretation of the problem, showing how to find the X and Y values where the tangent line intersects the curve. Finally, it demonstrates how to calculate the slopes for the tangent lines at specific points.
