A) \[\frac{1}{\cos x}\]
B) \[\frac{1}{\sin x}\]
C) \[\frac{1}{\tan x}\]
D) \[\cos x\]
Correct Answer: A
Solution :
In first case \[\tan \theta =\frac{{{B}_{V}}}{{{B}_{H}}}\] ..... (i) Second case \[\tan {{\theta }^{'}}=\frac{{{B}_{V}}}{{{B}_{H}}\cos x}\] ..... (ii) From equation (i) and (ii), \[\frac{\tan \theta '}{\tan \theta }=\frac{1}{\cos x}\]You need to login to perform this action.
