csc(x)cos^2(x)+sin^2(x)=csc(x)

Solución

csc (x) cos^{2} (x) + sin^{2} (x) = csc (x)

Solución

x = \frac{π}{2} + 2 πn

+1

Grados

x = 9 0^{\circ} + 36 0^{\circ} n

Pasos de solución

csc (x) cos^{2} (x) + sin^{2} (x) = csc (x)

Restar

csc (x)

de ambos lados

cos^{2} (x) csc (x) + sin^{2} (x) - csc (x) = 0

Re-escribir usando identidades trigonométricas

- csc (x) + sin^{2} (x) + cos^{2} (x) csc (x)

Utilizar la identidad pitagórica:

cos^{2} (x) + sin^{2} (x) = 1

cos^{2} (x) = 1 - sin^{2} (x)

= - csc (x) + sin^{2} (x) + (1 - sin^{2} (x)) csc (x)

Simplificar

- csc (x) + sin^{2} (x) + (1 - sin^{2} (x)) csc (x) : sin^{2} (x) - sin^{2} (x) csc (x)

- csc (x) + sin^{2} (x) + (1 - sin^{2} (x)) csc (x)

= - csc (x) + sin^{2} (x) + csc (x) (1 - sin^{2} (x))

Expandir

csc (x) (1 - sin^{2} (x)) : csc (x) - sin^{2} (x) csc (x)

csc (x) (1 - sin^{2} (x))

Poner los parentesis utilizando:

a (b - c) = ab - a c

a = csc (x), b = 1, c = sin^{2} (x)

= csc (x) \cdot 1 - csc (x) sin^{2} (x)

= 1 \cdot csc (x) - sin^{2} (x) csc (x)

Multiplicar:

1 \cdot csc (x) = csc (x)

= csc (x) - sin^{2} (x) csc (x)

= - csc (x) + sin^{2} (x) + csc (x) - sin^{2} (x) csc (x)

Sumar elementos similares:

- csc (x) + csc (x) = 0

= sin^{2} (x) - sin^{2} (x) csc (x)

= sin^{2} (x) - sin^{2} (x) csc (x)

sin^{2} (x) - csc (x) sin^{2} (x) = 0

Factorizar

sin^{2} (x) - csc (x) sin^{2} (x) : - sin^{2} (x) (csc (x) - 1)

sin^{2} (x) - csc (x) sin^{2} (x)

Factorizar el termino común

- sin^{2} (x)

= - sin^{2} (x) (- 1 + csc (x))

- sin^{2} (x) (csc (x) - 1) = 0

Resolver cada parte por separado

sin^{2} (x) = 0 or csc (x) - 1 = 0

sin^{2} (x) = 0 : x = 2 πn, x = π + 2 πn

sin^{2} (x) = 0

Aplicar la regla

x^{n} = 0 \Rightarrow x = 0

sin (x) = 0
