Respuesta :

csc² x - 1 = cot² x
1/ sin² x - 1 = cot² x
( 1 - sin² x ) / sin² x = cot² x
cos² x / sin² x = cot² x
cot² x = cot² x
Answer: True.

Answer:

True

Step-by-step explanation:

Given: [tex]\csc^2x-1=\cot^2x[/tex]

To find: False or True

Taking left side of equation

[tex]\Rightarrow \csc^2x-1[/tex]

[tex]\Rightarrow \dfrac{1}{\sin^2}-1[/tex]                          [tex]\because \csc x=\dfrac{1}{\sin x}[/tex]

[tex]\Rightarrow \dfrac{1-\sin^2x}{\sin^2}[/tex]

[tex]\Rightarrow \dfrac{\cos^2x}{\sin^2}[/tex]                          [tex]\because 1-\sin^2x=\cos^2[/tex]

[tex]\Rightarrow \cot^2x[/tex]

Thus, The left hand side is equal to right ahnd side.

Hence, The statement is true.
