(tÄn'jÉnt) A line, curve, or surface touching but not intersecting another. The ratio of the length of the side opposite an acute angle in a right triangle to the side adjacent to the angle. The tangent of an angle is equal to the sine of the angle divided by the cosine of the angle.
A tangent is a line that just touches a curve at one point, without cutting across it. Here is a tangent to an ellipse: Here is a cool thing: the tangent line has equal angles with the two lines going to each focus! Try bringing the two focus points together (so the ellipse is a circle) ... what do you notice? Section of a Cone. You can also get an ellipse when you slice through a cone (but not too steep a slice, or you get a parabola or hyperbola). In fact the ellipse is a conic section (a section of a cone) with an eccentricity between 0 and 1. Equation By placing an ellipse on an x-y graph (with its major axis on the x-axis and minor axis on the y-axis), the equation of the curve is:
