Thread: Quick Easy Question?

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

are you talking about identities ?

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

identities are squared and they are :

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

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