I tried to address the customer's problem, but she kept going off on a tangent and I couldn't understand what her true complaint was. The slopes of perpendicular lines have product −1, so if the equation of the curve is y = f(x) then slope of the normal line is, and it follows that the equation of the normal line is, Similarly, if the equation of the curve has the form f(x, y) = 0 then the equation of the normal line is given by[9], then the equation of the normal line is[8], The angle between two curves at a point where they intersect is defined as the angle between their tangent lines at that point.

The intuitive notion that a tangent line "touches" a curve can be made more explicit by considering the sequence of straight lines (secant lines) passing through two points, A and B, those that lie on the function curve. meeting a curve or surface at a point and having at that point the same direction as the curve or surface; -- said of a straight line, curve, or surface; as, a line tangent to a curve; a curve tangent to a surface; tangent surfaces. Give contextual explanation and translation from your sites ! As the point q approaches p, which corresponds to making h smaller and smaller, the difference quotient should approach a certain limiting value k, which is the slope of the tangent line at the point p. If k is known, the equation of the tangent line can be found in the point-slope form: To make the preceding reasoning rigorous, one has to explain what is meant by the difference quotient approaching a certain limiting value k. The precise mathematical formulation was given by Cauchy in the 19th century and is based on the notion of limit. See if you can get into the grid Hall of Fame ! See more. This leads to the definition of the slope of the tangent line to the graph as the limit of the difference quotients for the function f. This limit is the derivative of the function f at x = a, denoted f ′(a). Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content.

At most points, the tangent touches the curve without crossing it (though it may, when continued, cross the curve at other places away from the point of tangent). Pierre de Fermat developed a general technique for determining the tangents of a curve using his method of adequalityin the 1630s. It is the best approximation of the surface by a plane at p, and can be obtained as the limiting position of the planes passing through 3 distinct points on the surface close to p as these points converge to p.

Similarly, the tangent plane to a surface at a given point is the plane that "just touches" the surface at that point. In geometry, the tangent line (or simply the tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point—that is, coincides with the curve at that point and, near that point, is closer to the curve that any other line passing through that point. Two pairs of tangent circles. The geometric idea of the tangent line as the limit of secant lines serves as the motivation for analytical methods that are used to find tangent lines explicitly.
