Question

List the major trigonometric functions and the side lengths they relate.

Accepted Answer

$$\sin\;	heta = \frac{opposite}{hypotenuse}$$    

$$\cos\;	heta = \frac{adjacent}{hypotenuse}$$    

$$	an\;	heta = \frac{opposite}{adjacent}$$

$$\csc\;	heta = \frac{1}{\sin\;	heta} = \frac{hypotenuse}{opposite}$$    

$$\sec\;	heta = \frac{1}{\cos\;	heta} = \frac{hypotenuse}{adjacent}$$    

$$\cot\;	heta = \frac{1}{	an\;	heta} = \frac{adjacent}{opposite}$$
