Who is asking: Teacher I am stuck on a tangent? Is there a relationship between the tangent of a curve(line touching the curve at one point) and tangent (the trigonometric function)? Thanks for your help. Hi, Sure: Start with a circle whose radius is 1 and centre is C, a point A on the circle, and a point B on the line tangent to the circle at A. Then the TANGENT of angle ACB is the length of the segment AB intercepted by that angle on the tangent line.
