Definition and properties of the tangent line to an ellipse ... The blue line on the outside of the ellipse in the figure above is called the "tangent to the ellipse". Another way of saying it is that it is "tangential" to the ellipse. (Pronounced "tan-gen-shull"). It is a similar idea to the tangent to a circle.

To demonstrate that the value of the sine, cosine and tangent depends on the angle "b", let's study the three examples at the bottom of the figure. We are only going to discuss the sin(b) in these examples, but there are similar discussions for the cosine and tangent.

An interactive applet and associated web page that demonstrate a tangent to a circle. (not trig). The applet shows a circle and a tangent line. The center point and the tangent contact point are both draggable. As you drag each, the figure changes to ensure that the line is always tangential to the circle.

Explain why tan(x + 450 degrees) cannot be simplified using the tangent sum formulas but can be simplified by using the sine and cosine formulas. What is the difference between a trig equation that is an identity and a trig equation that is not an identity?
