You can put this solution on YOUR website! Find the values of the trigonometric functions of θ from the information given.
cos θ = − 3/5, θ in Quadrant III
-------
Note: If the angle is in QIII both x and y are negative.
-------------------
If cos = -3/5, x = -3 and r = 5
Then y = -sqrt[5^2-3^2] = -4
------
sin = y/r = -4/5
cos = x/r = -3/5
tan = y/x = 4/3
------
csc = -5/4
sec = -5/3
cot = 3/4
