How can you find out the relationships of triganometry functions?

Question: What are trigonometry functions and how can we identify them?

Answer: 

Trigonometric functions are functions that help relate sides of a triangle to its angles expressed through adjacent, hypotenuse and opposite, which is shown on the triangle below.

The trigonometric functions are: 

 The reciprocal functions of sine, cosine and Tangent is:

 

As you can see the reciprocals of sine, cosine and tangent is the opposite of their appointed trig function, or their trig function turned over.

 Lets try a Question:

What is the co function(Reciprocal function)of the trig function below:

Tangent(Tan): 4/5

The answer is Cot: 5/4 

the reason is because the trig function of tangent is opposite/ adjacent, since we are trying to find the reciprocal function we need to flip Tan over creating 5/4 or adjacent over hypothesis.

Try it Yourself:

What is the co functions of the trig functions below:

Cotangent: 8/10

Co secant: 5/ 8

Secant: 3/6
