Learn how to write the equation of a tangent line through a point of a function

The video tutorial explains the importance of using point slope form over slope intercept form to avoid mistakes. It discusses the concept of changing slopes and how to find the slope at a specific point using the limit definition. The tutorial walks through simplifying the limit expression to calculate the slope and demonstrates writing the equation of a line using point slope form, emphasizing its acceptability in exams.
