find all the remaining trigonometric functions x if:
cosx = 3/5 and tanx = -4/3
-----
cos is positive and tan negative in QIV where x is pos and y is neg.
----------------------
By definition, cos = x/r
Since cos(t) = 3/5, x = 3 and r = 5
Then y = -sqrt[5^2-3^2] = -4
----------------------------------
sinx= = y/r = -4/5
cotx= = x/y = -3/4
secx= = r/x = 5/3
cscx= = r/y = -5/4
