Question

please tell me fast​

Answer 1

Answer:

$\frac{1 - { \tan( \alpha ) }^{2} }{1 - { \cot( \alpha ) }^{2} }$

$\frac{ \frac{ { \cos( \alpha ) }^{2} - { \sin( \alpha ) }^{2} }{ { \cos( \alpha ) }^{2} } }{ \frac{ { \sin( \alpha ) }^{2} - { \cos( \alpha ) }^{2} }{ { \sin( \alpha ) }^{2} } }$

$\frac{ \frac{ \cos( \alpha ) - \sin( \alpha ) }{ { \cos( \alpha ) }^{2} } }{ \frac{ \sin( \alpha ) - \cos( \alpha ) }{ { \sin( \alpha ) }^{2} } }$

$\frac{ \frac{ \cos( \alpha ) - \sin( \alpha ) }{ { \cos( \alpha ) }^{2} } }{ - \frac{ \cos( \alpha ) - \sin( \alpha ) }{ { \sin( \alpha ) }^{2} } }$

$- \frac{ { \sin( \alpha ) }^{2} }{ { \cos( \alpha ) }^{2} }$

$- { \tan( \alpha ) }^{2}$

I think, the RHS would be -tan.^2(α)

or, the question is wrong. I have used α but we can use theta also
