Question

Sabendo que cossec x = -2, determine o valor de sen²x.

Answer 1

$\sin^2x=\frac{1}{\csc^2x}\\\\\sin^2x=\frac{1}{(-2)^2}\\\\\sin^2x=\frac{1}{4}$

Answer 2

Resposta:

$sen^{2} x$ = $\frac{1}{4}$

Explicação passo-a-passo:

se cossec x = -2, logo $\frac{1}{sen x}$ = -2

$sen x$ = $-\frac{1}{2}$

$sen^{2} x$ = $\frac{1}{4}$
