<PRE><B>Question 949485</B>
prove the identities 	1/(&amp;#12310;tan&amp;#12311;^2 &amp;#1012;+1)+1/(&amp;#12310;cot&amp;#12311;^2 &amp;#1012;+1)=1

i know tan^2 &amp;#1012;+1 = sec^2 &amp;#1012; 
and cot^2 &amp;#1012;+1 = csc^2 &amp;#1012;
 then sec^2 &amp;#1012; is (1/cos&amp;#1012;)^2
and csc^2 &amp;#1012; is (1/sin&amp;#1012;)^2
cos^2 &amp;#1012; + sin^2 &amp;#1012; = 1 
please help ... to prove
===============
1 more step:
1 = 1
sin^2 + cos^2 = 1 is the Pythagorean Identity.
----
i know tan^2 + 1 = sec^2
Multiply thru by cos^2
sin^2 + cos^2 = 1
