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
