**In case some of you are last-minute**

*studiers*(excluding myself, obviously... Eh-hm, eh-hm cough, cough), I will elaborate just a*tad*(for I also have a memory aid to make) on what the test may be about. Here is the orginial power point.

**Six Trigonometric Ratios**

**Sine = Opposite/Hypotenuse****Cosine = Adjacent/Hypotenuse****Tangent = Opposite/Adjacent****Cosecant = Hypotenuse/Opposite****Secant = Hypotenuse/Adjacent****Cotangent = Adjacent/Opposite**

**As you may already know, numbers 1 and 4, 2 and 5 and 3 and 6 are reciprocals of each other. Remember the**

*sohcahtoa and choshacao*! Here is my post for this subject.

**Radians and Degrees**

**Everything you need to know is right here. I'm just too lazy to re-copy it all onto here. :)**

**The**

*B17*

**Alright, the way I remember the different quadrants:**

**Quadrant #1: Simple; 6, 4, 3 as denominators.****Quadrant #2: The pattern of denominators to numerators (2,2,3,3,4,5,6).****Quadrant #3: The second half of the pattern (7,6,5,4,4,3,3,2).****Quadrant #4: Same denominators as usual (3, 4 and 6) and use the n = 2d - 1 formula for the numerators.**

**The Sine & Cosine Function**

So, there are a lot of things to remember about this!

**Definition****Remember cos is x and sin is y****The basic functions:****y = asinb(x-h)+k****y = acosb(x-h)+k****The properties**

And that is all! Good studying and hope you all do well on the test. :)
