Question

Necesito ayuda urgenteeeeee

Answer 1

Explicación paso a paso:

$\frac{tan\alpha*cos\alpha }{cos\alpha*sen\alpha} \\\\\frac{tan\alpha }{sen\alpha } \\\\\frac{sen\alpha/cos\alpha }{sen\alpha } \\\\\frac{1}{cos\alpha } \\\\sec\alpha$

__________________________________________________

$sec\alpha*cosec\alpha \\\\\frac{1}{cos\alpha } *\frac{1}{sen\alpha } \\\\\frac{1}{cos\alpha *sen\alpha } \\\\\frac{1}{cos\alpha *sen\alpha }*\frac{2}{2} \\\\\frac{2}{2cos\alpha *sen\alpha }\\\\\frac{2}{sen(2\alpha) }\\\\2cosec(2\alpha)$

__________________________________________________

$sen^{2} \alpha +cosx^{2} \alpha -1\\\\1-1\\\\0$
