Identitas Trigonometridengan cara

Penjelasan dengan langkah-langkah:

$frac{ csc( alpha ) }{ cos( alpha ) } - frac{ cos( alpha ) }{ sin( alpha ) } = tan( alpha ) \ frac{ frac{1}{ sin( alpha ) } }{ cos( alpha ) } - frac{ cos( alpha ) }{ sin( alpha ) } = tan( alpha ) \ frac{1 - cos( alpha ) cos( alpha ) }{ sin( alpha ) cos( alpha ) } = tan( alpha )$

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