find the angle and all other trigonometric functions of a
right triangle if sec θ = 10/6
------------------
angle = cos^-1(6/10) = 53.13 degrees
-----------------------------------------
If sec(theta) = 10/6, r = 10 and x = 6
---
Then y = sqrt(10^2-6^2) = sqrt(64) = 8
-----------------
So,
sin(theta)= y/r = 8/10
cos(theta) = x/4 = 6/10
tan(theta) = y/x = 8/6
----
csc , sec, and cot are the inverse of sin, cos, tan
