When you're tangent at point A, that means your tangent to the radius at that point.

Tangent at This Point

A tangent intersects the circle at exactly one point.

And we know, that this line is tangent at point A.

Tangent

Tangent

A horizontal line would be tangent to the curve at y equals 0.

So Line L is tangent. Tangent to the circle.

In the figure below, line AB is tangent to circle O at point A.

The line tangent to a curve

I'm trying to do a tangent.

So this should be a tangent.

RB is tangent to a circle.

So this becomes a tangent line.

Hyperbolic tangent

Arc tangent

Hyperbolic tangent

This is the slope of the tangent at any point x.

Construct a circle tangent to this line

So what is a tangent of x?

I'm trying to draw a tangent line.

Hyperbolic arc tangent

Inverse hyperbolic tangent

What is tangent?

The tangent slope.

Well that's tangent.

It's not tangent.

So if I were to draw the tangent line here the tangent

So if I were to draw a tangent line right there, this line is normal to that tangent line.

This is the slope at any particular x0 of the tangent line.

And it's tangent at point B, so it's perpendicular to the radius at that point.

And the slope at a given point would be the same as the slope of a tangent line.

And the line, it really isn't a tangent.

Show the tangent field

We know that when a line is tangent to a circle, it's perpendicular to the radius at that point.

Or the slope of the tangent line at that point of the curve.

Function to calculate the tangent of a given angle

You're off on a tangent. Your values are confused.

Bless my soul alive! she said, going off at a tangent ain't you done them taters yet, Millie?
