DOMAIN mei DBT

2tanΠx >0 and ≠1 ?

ya i did that.......

apart frm that ne conditions .............

i.e. mainly 4 [2tanpix]

i dont think any restrictions on that ... except when tan(Πx) is not defined i.e. Πx ≠(2n+1)Π/2

[2tanÎ x]. As this is under log function , following conditions must be applied

x ≠n (ε N)

2tanΠx ≥ 2 => Πx ε [nΠ+Π/4,(2n+1)Π/2) {nεN} => x ε [n+1/4,n+1/2) {nεN}

Therefore only the fourth option matches the condition nεN. hence answer is (d)

correct me if i am wrong !

The ANS givn is A,C [2]

I'm sorry, my answer is not the final one, we must also find the domain of (x²+2x-3)/(4x²-4x-3). and then find the intersection of these two domains to get the final domain.

I think u can carry on the further simplification urself. :)
