SP 7: Unit Q Concept 2: Finding trig functions using identities

Original Problem: 

tan(x) = -1, cos(x)= 1


In this step above we have the substitution of cot that substitutes with 1/tan. 
In this next step we have the identity that includes both tan and sec. This identity allows us to simplify to a one term answer. 
 Next we come to another identity to where both cot and csc are found together. This identity allows the answer to come out to be one term and the steps include: adding, and square rooting. 
This following step shows the substitution of csc to sin. the substitution is to solve with the answer known for the answer we are in search of. 

These are the answers we came to finding with all the steps above.
