In math class, I am currently learning about Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent. We have also just started a lesson on the unit circle. I have all the coordinates for the Unit Circle all plotted out for 30, 45, 60, 90, 120, 135, 150, 180, 210, 225, 240, 270, 300, 315, 330, and 360 degrees.
How do I find the Sin of 30 degrees? How do I find the Cosine of 30 degrees? How do I find the tangent of 30 degrees? The points for 30 degrees are, (square root of 3 divided by 2, 1/2).
Here is a link to the unit circle that I found on the internet:
