Answer 1

IDENTIDADES TRIGONOMÉTRICAS FUNDAMENTALES

sec . sen + csc . cos - tg

$\sec \left(x\right)\cdot \sin \left(x\right)+\csc \left(x\right)\cdot \cos \left(x\right)-\tan \left(x\right)$
$\sec \left(x\right)\sin \left(x\right)=\tan \left(x\right)$
$\csc \left(x\right)\cos \left(x\right)=\cot \left(x\right)$
$\tan \left(x\right)+\cot \left(x\right)-\tan \left(x\right)$
$\cot \left(x\right)$
