A tangent is a line that touches a curve at a point. Start by picking two points, then enter elevations for each point, and the result will be returned in the text window. The … For non-linear functions, the rate of change of a curve varies, and the derivative of a function at a given point is the rate of change of the function, represented by the slope of the line tangent to the curve at that point. The formula to determine the distance (D) between 2 different points is: \( Distance (d) = \sqrt {(x₂ – x₁)^2 + (y₂ – y₁)^2 } \). The point where the curve and the line meet is called a point of tangency. X 2. Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as.
