Question

Simplify ( cot² x - 11 + cot² x ).

a) ( tan² x )
b) ( cot² x )
c) ( 1tan² x )
d) ( sin² xcos² x )

Answer 1

To simplify the expression (cot² x - 11 + cot² x), combine the like terms to get 2 cot² x - 11.

Step-by-step explanation:

To simplify the expression (cot² x - 11 + cot² x), we can combine like terms. Since both terms have cot² x, we can add them together to get 2 cot² x. The simplified expression is therefore 2 cot² x - 11.
