Question

Evaluate (sec^2tea -1)(cosec^2teta-1)

Answer 1

Step-by-step explanation:

$identities \: are = \\ 1 + {\tan(x)}^{2} = { \sec(x) }^{2} \\ 1 + { \cot(x) }^{2} = { \csc(x) }^{2}$

$your \: answr \: is \\ ({ \tan(x) }^{2} )( { \cot(x) }^{2} ) \\ this \: equals \: to \: 1 \: following \: identity$
