I'm trying to write a lesson plan on into to calculus, it is to start off talking about gradient of a secant, I'm trying to find an interesting (mathematical) way to start the lesson and I was going to define the term secant and show the different types, I once remember being told that the diameter is a secant, but I want to be correct and prepared for this lesson....
Can I prove it with the formula for calculating the gradient of a secant?

A secant is just a line that crosses through a circle at two points, so there's really no reason why it can't pass through the center of the circle at some specific time.

I think it isn't. =)
A secant should be a line that intersects the circle in two points. The diameter of a circle, however, is only a segment so it should be classified as a chord.
Please correct me if I'm wrong. Just wanted to share my opinion. =)

No, normally, a diameter is a chord; thus, it can't continue on as a line or ray. So, no, a diameter can't be a secant.

yes use the fourmula. pie times dimeter. dimeter is the length of the middle of the circle and pie equals 3.14 so say i have a circle and the center measures 5 inches i would take a caculator and put in 5 times 3.14 and u will get some answer
