The slope of the secant line would be ( ) ( ) ( ) ( ) ( ). Imagine that points R and S in figure 29get closer and closer together. The closer the points become the closer the secant line would approximate the tangent line. As the value of h goes to 0 (h or run or the horizontal change), we would approximate the slope of the tangent line.

The line tangent to y = x2 at the point (2,4) has slope 4. We can use the point-slope formula for a line to find an equation of this tangent line: y −y0 = m(x −x0) ⇒y −4 = 4(x −2) ⇒y = 4x −4 Practice 4. Use the method of Example 2 to show that the slope of the line tangent to the graph of y = f(x) = x2 at the point (1,1) is mtan = 2.

Now to determine the equation of the tangent we again use Defini-tion 12.1. The formula is. y p(a) = mtan(x a). In our case a = 1 and p(1) = 7 and we just found that mtan = 9. So. 7 = 9(x. ) y = 9x 2. Again, very straightforward if we know the definitions of the terms. An Alternative Formula for Tangent Slope.

culation of tangents using the tangent formula To calculate the slope of any point on the line, we draw a tangent to it and calculate the value of tan of the angle it makes with the base. A tangent to a curve is a straight line that touches the curve at a given point and represents the gradient of the curve at that point. Fig. 1.
