sin x = -4/5ths find the exact va;ue of each of the remaining trigonometric functions
---------
sin(x) = -4/5, not -4/5ths
----
csc = 1/sin
------
cos%28x%29+=+sqrt%281+-+sin%5E2%28x%29%29
cos(x) = 3/5 in Q3 or -3/5 in Q4
----
sec = 1/cos
tan = sin/cos
cot = cos/sin
----------------
You have to know what quadrant to get a single value for cosine, tangent, cotangent & secant
