First, you determine whether the two functions intersect, i.e. whether they have a common point. If so, you determine the slope of both functions at this point. To determine the slope, you find the first derivative of both functions and insert the x-coordinate of the common point into the derivative. If the two derivatives have the same slope, then there is a point of contact ----------------------------------------------------------- CHAPTER 0:00 Basics 0:45 Conditions Point of contact 1:21 Example calculation ---------------------------------------------------------- YOUTUBE If you liked the video, I would be pleased if you subscribe to Mister Mathe! ----------------------------------------------------------- INSTAGRAM @Mister.Mathe ----------------------------------------------------------- #intersection, #point of contact, #angle of intersection, #angle of intersection, #tangent equation, #tangent, #point of contact, #function, #math, #function equation, #slope angle, #slope, #calculate slope #function, #calculate slope, #slope angle, #derivative, #derivative, #differential calculus, #differentiation, #derivative rules, #constant rule, #power rule, #factor rule, #differential quotient, #difference quotient, #increase
