<PRE><B>Question 758214</B>
A function value and a quadrant are given. find the other function values give the exact answers.

 cos theta = 9/41
----
Note: You mentioned no quadrant.  I&#39;ll assume is is QIV where y is negative.
-----
Since cos = x/r = 9/41, x = 9 and r = 41
Solve for &quot;y&quot;
---
y = -sqrt{41^2-9^2] = -40
--------- 
what is the sin = y/r = -40/41
------- 
what is the tan = y/x = -41/9 = -4.556
