Thank you for the answers to my last question, Tangent? What's that? Unfortunately, as I said before, I am an elementary student. I  can't understand it as well as a high schooler. Can someone give a simpler answer to reply to the question, "what's a tangent?"

There are two entirely different meanings to the word "tangent"

 

You were given what I'd call the second one.  A line that touches a curve at exactly one point.

 

The definition you are probably after is entirely different

 

Consider the following right triangle

The "tangent" of the angle \(\theta\) is given by

 

\(\tan(\theta) = \dfrac{\text{length of opposite side}}{\text{length of adjacent side}}\)
