You can put this solution on YOUR website! the point p(x,y) on the unit circle that correspondsto a real number t is given. find the values of the indicated trigonometric function at t.
(-sqrt7/4,3/4)
---------------
r = sqrt[(7/16)+(9/16)] = sqrt(1) = 1
-----------
sin = y/r = (3/4)
cos = x/r = -sqrt(7)
tan = y/x = -3/sqrt(7)
-----------
csc, sec, and cot are the inverse of sin, cos, and tan
