# Math Help - Quick Easy Question?

1. ## Quick Easy Question?

Which trig function is 1+cos? Don't remember....

2. are you talking about identities ?

3. Yes... I am talking about identities... and another question does anyone happen to know the identity of 1/sinx?

4. identities are squared and they are :

$sin^{2}x+cos^{2}x=1$
$1+cot^{2}x=cosec^{2}x$
$tan^{2}x+1=sec^{2}x$

$1/sen(x)=cosec(x)$
