- 1A straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.More example sentences
- He noticed that he could draw three straight lines, or tangents, that each touched all three circles.
- Since normals to a straight line never intersect and tangents coincide with the curve, evolutes, involutes and pedal curves are not too interesting.
- One of his most important results explains how the 28 double tangents of the plane quadric are related to the 27 straight lines of the cubic surface.
- 2A completely different line of thought or action: Loretta’s mind went off at a tangentMore example sentences
- Look at that, we started with the opening credits and I went off on a tangent.
- Otherwise, people will start going off on different tangents, and you can't have that.
- Thankfully, he went off on a different tangent.
- 3 Mathematics The trigonometric function that is equal to the ratio of the sides (other than the hypotenuse) opposite and adjacent to an angle in a right-angled triangle.More example sentences
- The first tabulates logarithms of the sine, cosine, tangent and cotangent functions at 1 intervals and shows how to solve triangles using logarithmic functions.
- The proof needs another formula about tangents of angles that we have not covered on the Pi and the Fibonacci Numbers page.
- If the tangent of an angle is a/b then the cotangent of that angle is b/a.

- (Of a line or plane) touching, but not intersecting, a curve or curved surface: this curve is tangent to the average cost curveMore example sentences
- Smooth infinitesimal analysis embodies a concept of intensive magnitude in the form of infinitesimal tangent vectors to curves.
- Construct two tangent circles 1 and 2 and the line L through their centers.
- The Kummer surface has 16 isolated conical double points and 16 singular tangent planes and was published in 1864.
- More example sentences
- Depending on the geometry type, you can preserve projection, plane, position, tangency, curvature, and any valid combination of these characteristics.
- For complementary resources, this combination is also the point of tangency between an isocline and the constraint curve.
- Two tangents of a parabola are divided into segments of like proportion by a third and this third is divided in the same proportion by its point of tangency.
late 16th century (in sense 3 of the noun and as an adjective): from Latin tangent- 'touching', from the verb tangere.
