Respuesta:
[tex]=\frac{\sin \left(x\right)-2\cot \left(x\right)+\cot \left(x\right)\cos \left(x\right)+\csc \left(x\right)}{1-\cos \left(x\right)}[/tex]
Explicación paso a paso:
[tex]\frac{1-\cos \left(x\right)}{\sin \left(x\right)}=-\cot \left(x\right)+\csc \left(x\right)\\[/tex]
[tex]=\left(\csc \left(x\right)-\cot \left(x\right)\right)+\frac{\sin \left(x\right)}{-\cos \left(x\right)+1}\\[/tex]
Convertir a fracción:
[tex]=\frac{\sin \left(x\right)-\cot \left(x\right)\left(1-\cos \left(x\right)\right)+\csc \left(x\right)\left(1-\cos \left(x\right)\right)}{1-\cos \left(x\right)}[/tex]
Quedando:
(1 - cos∅)/sen∅ + (sen∅)/ (1-cos∅)
Usando un triángulo notable
30-60 :
( 1 - √3/2) / 1/2 + (1/2)/(1-√3/2)
2 - √3 + 2+√3 = 4
4 = csc²x
Respuesta = csc²x
espero t sirva bai :) .
