Answer 2

$\mathtt {\underline \green {answer}}$

There are two meanings, the tangent of an angle (or the tangent function) and a tangent to a curve. The answers that talk of the tangent of an angle are correct so I’ll concentrate on a tangent to a curve.

A curve has a tangent at a point if it meets the curve at that point and has the same gradient* as the curve where it meets**. We often say it “touches the curve” but that just means it is a tangent. Other answers go wrong when they say the tangent meets the curve at only one point. That’s incorrect as it can meet the curve at any number of other points, it is just at the point where it is a tangent that matters.

For there to be a tangent, at a point, the curve cannot have a corner at that point.

*I’ll leave the definition of “gradient” to your calculus courses.

**Two curves can also be tangential to one another. They are tangential if they meet at a point where they have the same gradient.
