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