WebThis video introduces how sine and cosine are defined using the unit circle. The video is pitched at a Year 10 level for Australian Mathematics. WebI think the unit circle is a great way to show the tangent. While you are there you can also show the secant, cotangent and cosecant. I do not understand why Sal does not cover this. Using the unit circle diagram, draw a line “tangent” to the unit circle where the hypotenuse contacts the unit circle.
