The first step to finding the equation of a secant line is to find its slope . How to Find Slope of a Secant LineTangent to a Curve. A tangent line is a line that touches a curve at a single point and does not cross through it. The point where the curve and the tangent meet is called the point of tangency. We know that for a line y=mx+c y = mx+ c its slope at any point is m m. The same applies to a curve. Solution. We can use Equation, but as we have seen, the results are the same if we use Equation. mtan = limx → 2f ( x) − f ( 2) x − 2 Apply the definition. = limx → 21 x − 1 2 x − 2 Substitute f(x) = 1 x and f(2) = 1 2. = limx → 21 x − 1 2 x − 2 ⋅ 2x 2x Multiply numerator and denominator by 2x to simplify fractions.In this case, the equation of the tangent at the point (x 0, y 0) is given by y = y 0; If θ →π/2, then tan θ → ∞, which means the tangent line is perpendicular to the x-axis, i.e., parallel to the y-axis. In this case, the equation of the tangent at (x 0, y 0) is given by x = x 0; Equation of Tangent and Normal Problems Your job is to find m, which represents the slope of the tangent line.
