Things like 0 degrees and 90 degrees are really easy if you just imagine a degenerate triangle with one side of length 0 (or almost zero if you prefer). Stuff like 210 degrees is easy to do by using the unit circle to figure out the signs and the above arguments to do the hard parts.

The unit circle is a great way to remember your trig values. Remember that it's just a circle with a radius of one... but, it gives us such cool info! If you haven't already, it's time to memorize this thing! Here are the main angles: RADIANS

The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here. Have a try! Move the mouse around to see how different angles (in ...

Going around the unit circle, the cosine is the x-coordinate and the sine is the y-coordinate. So for the multiples of 90° ($\pi/2$), these are easy: at 0, the x-coordinate is 1 …
