Question

cosec2 a = 1 + cotg2 a

Answer 1

Respuesta:

$\csc ^2\left(x\right)=1+\cot ^2\left(x\right)$

$\csc ^2\left(x\right)=1+\frac{\cos ^2\left(x\right)}{\sin ^2\left(x\right)}$

$\csc ^2\left(x\right)=\frac{\sin ^2\left(x\right)+\cos ^2\left(x\right)}{\sin ^2\left(x\right)}$

$\csc ^2\left(x\right)=\frac{1}{\sin ^2\left(x\right)}$

$\csc ^2\left(x\right)=\csc ^2\left(x\right)$
