|
List - I |
List - II |
||
|
A) |
\(\rm Sin ^{-1} \left(\frac{2\sqrt2}{3}\right) + Sin^{-1}\frac{1}{3}\) |
I) |
kπ ± (-1)k \(\frac{π}{6}\), k ∈ ℤ |
|
B) |
\(\rm Sin ^{-1} \left(\frac{(-1)^n}{2}\right) ,n ∈ ℤ\) |
II) |
kπ ± 1, k ∈ ℤ |
|
C) |
\(\rm Tan^{-1} \left(sec\frac{π}{2}+tan \frac{π}{4}\right) \) |
III) |
\(\frac{3}{2}\) |
|
D) |
Sin-1 |sin x| = \(\rm \sqrt{sin^{-1}| \ sin\ x|}\Rightarrow x ∈ \) |
IV) |
