find the value of

is it ∞ ?

that only i want to know

the ans is "none of these"

that means 2/3, 1, 1/4 are all incorrect

btw, how can u say that surely and other options are incorrect???

1/4

1

2/3

none of these

See, my reasoning was as x→π2, tan²x tends to infinity, however, the sum inside the bracket tends to -2. I'm sorry, it should've been -∞!

So since its not an indeterminate form, it should be -∞!

thanks

i just forgot that ∞ * a = ∞ which is not indeterminate

done

bye

its simply ∞ x -2
