Learning the unit circle A few tricks
One trick to learning the unit circle is your hand. You can use your left hand (or right) to help you remember the angles. This can be very useful if you are quickLay trying to remember an angle on a test or assessment.
Once you know one quadrant of the unit circle, it is easy to figure out the rest. But it's important to know the difference between cosine and sine and which are positive and which are negative at certain points.
This is how your find the point of any angle on the unit circle.
One of the coolest things about the unit circle, is that once you learn all the angle, you can easily find the value of that angle. This is the mnemonic device for the unit circle. Pretty cool how math works sometimes! Hope these tips helped :)
