$\left(1+\cos\left(x\right)\right)\left(1\:-\cos\left(x\right)\right)=sen\left(x\right)^2$
$\frac{\cos}{\sec}=\cos^2$
$\csc\left(x\right)=\frac{1}{\sin\left(x\right)}$
$\sin x\:\tan x+\cos x=\sec x$
$sen\left(a\right)=\frac{1}{csc\left(a\right)}$
$sec\:x+tan\:x=\frac{cos\:x}{1-\:sen\:x}$
$\frac{sinx-sin^3x}{\cos^2x}=\frac{1}{\csc x}$
