Question

identidades trigonométricas

(1+tan^2(x))/csc^2(x)=tan^2(x)

Answer 1

Explicación:

$\frac{1 + {tan}^{2}(x) }{ {csc}^{2}(x) } = {tan}^{2} (x) \\ \frac{ {sec}^{2}(x) }{ {csc}^{2}(x) } = {tan}^{2} (x) \\ \frac{ \frac{1}{ {cos}^{2} (x)} }{ \frac{1}{ {sen}^{2}x) } } = {tan}^{2} (x) \\ \frac{ {sen}^{2}(x) }{ {cos}^{2}(x) } = {tan}^{2} (x) \\ {tan}^{2} (x) = {tan}^{2} (x)$
