For for any value of m Eq. Recall that when two lines are perpendicular their slopes are. Y f x o f x o x x o The normal line to a curve at a particular point is the line through that point and perpendicular to the tangent.
Calculate the Slope of the.
This calculus video tutorial shows you how to find the slope and the equation of the tangent line and normal line to the curve function at a given point. Determine if the slope if positive increasing or negative decreasing Step Two. Because the slopes of perpendicular lines neither of which is vertical are negative reciprocals of one another the slope of the normal line to the graph of f x is. 2 represents normal to the given parabola.
