Question

valor de las 6 razones trigonométricas de un ángulo de 90°​

Answer 1

Explicación paso a paso:

$\sin(90) = 0$

$\cos( \alpha ) = \sqrt{1 - { \sin( \alpha ) }^{2} }$

$\cos( 90) = 1$

$\tan( \alpha ) = \frac{ \sin( \alpha ) }{ \cos( \alpha ) }$

$\tan(90) = \frac{0}{1} = 0$

$\cot( \alpha ) = \frac{1}{ \tan( \alpha ) }$

$\cot(90) = \frac{1}{0} = -$

$\sec( \alpha ) = \frac{1}{ \cos( \alpha ) }$

$\sec(90) = \frac{1}{1} = 1$

$\csc( \alpha ) = \frac{1}{0} = -$
