Bro this step is Wrong.

Answer 2

$\huge{\red{\mathtt{\underline{Answer:}}}}$

Iske beech me aapne ek step mis kiya hai. .

theta ki jagah x lera hu

a² - b² = ( a + b ) ( a - b )

→ $\frac{(sec\:x + tan\:x)-(sec\:x + tan\:x)(sec\:x-tan\:x}{tan\:x-sec\:x+1}$

Iss step me common liya gya hai .

Common brackets ke bahar waale + ya - ke sign pehle or baad me se liya gya haii .

Isme sec theta + tan theta ko common liya & [1 - ( sec x - tan x ) ] bacha .

Hindi me likha taaki samajh aaye aapko
