A) 36
B) 81
C) 144
D) 256
Correct Answer: A
Solution :
[a] \[\frac{\Delta }{{{h}^{2}}}=\left| \begin{matrix} \tan x & \frac{\tan (x+h)-\tan x}{h} & \frac{\tan (x+2h)-\tan x}{h} \\ \tan (x+2h) & \frac{\tan x-\tan (x+2h)}{h} & \frac{\tan (x+h)-\tan (x+2h)}{h} \\ \tan (x+h) & \frac{\tan (x+2h)-tan(x+h)}{h} & \frac{\tan x-\tan (x+h)}{h} \\ \end{matrix} \right|\]You need to login to perform this action.
