What is ^2 ( ⁻¹ 2 )+ ^2 ( cosec ⁻¹ 3 ) equal to?
Options
- A11 12
- B11 24
- C7 24
- D1 24
Correct answer
B. 11 24
Step-by-step solution
aligned & Suppose I = ^2 ( ⁻¹ 2 )+ ^2 ( cosec ⁻¹ 3 ) & I = ^2 (60^ )+ ^2+ ( ⁻¹ 9-1 ) & cosec ⁻¹ t = ⁻¹ t ^2-1 & I = 1 3 + ^2 ( ⁻¹ 1 8 )= 1 3 + 1 8 = 11 24 aligned
