Question

$\frac{cosa - sina + 1}{cosa + sina - 1} = coseca + cota$
​

Answer 1

Steps of doing

• simplify LHS and RHS seperately
• Take LHS and Divide sinA in both LHS and RHS
• Simplify and you will find the identity of cosec^2A-cot^2A=1
• Then take common in numerator
• you will find something same in numerator and denominator cut it
• Then LHS is equal to the RHS

Note

Observe the question properly don't give up without doing any question of maths
