<PRE><B>Question 854929</B>
Given that theta is an acute angle and tan theta equals u, find the other trigonometric functions of the angle theta in terms of u.
--------
tan(t) = u/1 ; So, y = u and x = 1
Then r = sqrt(u^2+1)
--------------------------------
sin(t) = y/r = u/sqrt(u^2+1)
cos(t) = x/r = 1/sqrt(u^2+1)
tan(t) = y/x = u
-------
csc(t) = r/y = sqrt(u^2+1)/u
sec(t) = r/x = sqrt(u^2+1)/1
cot(t) = x/y = 1/u
---------------------------
