Question

ayudame porfis ☹️ identidad trigonometríca ​

Answer 1

Explicación paso a paso:

$(1 - { \cos(A) }^{2} )(1 + { \cot(A) }^{2} ) = 1 \\ ({ \sin(A) }^{2} )( { \csc(A) }^{2} ) = 1 \\ {( \sin(A) \csc(A)) }^{2} = 1 \\ {1}^{2} = 1 \\ 1 = 1$

Se Aplico las siguientes Identidades Trigonometricas

$\boxed{1 + { \cot(A) }^{2} = {\csc(A) }^{2}} \\ \boxed{ 1 - {\cos(A) }^{2} = { \sin(A) }^{2} }\\ \boxed{\sin(A) \csc(A)) =1}$
