Secant Line Problems
It is our average rate of change from this point to this point. So it is our average rate of change, or you could say it's the slope of the secant line. So the secant line would look something like this. Slope of the secant line, so this right over here is slope of secant line between from f of negative a to 0 comma 1.
A secant line from the Latin Secare, to cut connects two ore more points on a curve. The following image shows a secant line that connects two points, Example Problem Find the limit of sec x as x approaches 1. Step 1 Draw a table . Include a few small values around your x-value. In this table, I'm finding the limit at the point c
A tangent line just touches a curve at a point, matching the curve's slope there. From the Latin tangens quottouchingquot, like in the word quottangiblequot. A secant line intersects two or more points on a curve. From the Latin secare quotcut or severquot They are lines, so extend in both directions infinitely.. Circle. On a circle they look like this Theorems. There are three theorems of interest here
, then that line is called a . secant line. We can easily calculate the slope of this line since we know the points P and Q. If we move the above secant line so that it only crosses the curve at point P, it is then called a . tangent line. Finding the slope of this line is the subject of this module. Critical Thinking Questions. 1.
tangent and secant lines is greatest where the graph of fx is curved. If the graph of y fx is sharply curved, the value of x must be very close to 0 for the secant line to be close to the tangent line. You may also have noticed that the di erence between the slope of the secant and the slope of the tangent line was greater when the
Approximate the slope of the tangent line to 92f92 at 92x 192 by finding the slope of the secant line through 921,192 and the following points. Sketch a few secant lines on the graph above as well.
change of x, i.e. the slope of the secant line to a curve fx from x a to x b is given by fb fa b a 3 How can we use secant lines to help us nd the slope of tangent lines? If we nd the slope of the secant lines from x a to x b as b gets closer and closer to a, then the slope of the secant lines gets closer and closer to the slope

Read the problem and identify the desired results. Underline or circle the quantity or quantities
Here is a set of practice problems to accompany the Tangent Lines and Rates of Change section of the Limits chapter of the notes for Paul Dawkins Calculus I course at Lamar University. x92 compute accurate to at least 8 decimal places the slope, 92m_PQ92, of the secant line through points 92P92 and 92Q92. -3.5-3.1-3.01-3.001-3.0001-2
Another secant line is drawn through 92a, fa92 and a different point to show the dependence on the points we select.
