Question 1056765
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
------------------
