# Tangent to a Tangent

Consider a tangent m on some point on the graph of a curve f(x). What is the tangent to any point on m? Or, more simply what is the tangent to a straight line?

I believe it is the line itself,right?

Sort by:

The tangent on $$f(x)$$ has equation $$f'(x)$$. You cant say that there is a point that is tangent to a curve, the line which contains $$m$$ is tangent. · 4 years ago
