Question 973922
Use the Pythagorean Theorem to determine the third side and then find the two trigonometric functions of theta. tan theta and sec theta 
csc theta = 4
=================
sin = 1/csc = 1/4
------
{{{cos(t) = sqrt(1 - sin^2(t)) = sqrt(15)/4}}}
sec = 1/cos = {{{4sqrt(15)/15}}}
----
tan = sin/cos = {{{sqrt(15)/15}}}
=======================
The signs might be + or minus, no quadrant info was given.
