Question 824411:  Find the five trigonometric functions values using the fundamental identities give cot(x)=4/3

You can  put this solution on YOUR website! Find the five trigonometric functions values using the fundamental identities give cot(x)=4/3 
----- 
Since cot is positive, x could be in QI or in QIII. 
I'll assume that x is in QI where x, y, and r are all positive. 
---------------------- 
cotangent = x/y 
--- 
Since cot(x) = 4/3, x = 4 and y = 3. 
Then r = sqrt[4^2+3^2] = 5 
------ 
Answer: 
sin = y/r = 3/5 
cos = x/4 = 4/5 
tan = y/x = 3/4 
csc = r/y = 5/3 
sec = r/x = 5/4 
cot = x/y = 4/3
