Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.how did he get pi/2 coz therees still sin alpha and cos alpha in the bracket
i understood this ( below image)
also T = tan x/2 for people who are wondering
some tomfoolery going on here
let me see
oh bruh just substitute the values
tan^-1(tan(infinity) is pi/2 and subtract by lower limit you'll get tan^-1(tan α)
what's given is correct I think you forgot to substitute the values
and btw soja bhai
I think this might be your doubt
mummy bolti hai neend nahi hone se jo padhre wo bhi yaad nahi hota (I will scroll reels till 3am despite having college tomorrow)
oh and x is positive finite value for infinity/x=x I forgot to mention
it must be mentioned that alpha lies in 1st quadrant in the question somewhere
that is why tan^-1(tan α) = α
could you send the image of the main question? @BlindSniper (BS)
not my thread so idk
you can close this thread now
if your doubt is cleared @🏎
thankss @BlindSniper (BS)
