You can put this solution on YOUR website! Let 7,-2
 be a point on the terminal side of
 θ
 .
 Find the exact values of
 cosθ
 ,
 cscθ
 , and
 tanθ
 ---------------
 x = 7 ; y = -2 ; r = sqrt[7^2+2^2] = sqrt(53)
 --------------------------------
 cos(t) = x/r = 7/sqrt(53)
 csc(t) = r/y = -sqrt(53)/2
 tan(t) = y/x = -2/7
 ------------------
