A) \[\tan \,\delta cosec\,\theta \]
B) \[\tan \,\delta \sin \,\theta \]
C) \[\tan \,\delta \cos \,\theta \]
D) \[\tan \,\delta \sec \,\theta \]
Correct Answer: A
Solution :
\[\tan \delta =\frac{V}{H}\] \[\tan {{\delta }_{1}}=\frac{V}{H\,\cos (90-\theta )}\] \[=\frac{\tan \delta }{\cos (90-\theta )}\,\,\,=\,\,\tan \delta \,\cos ec\,\theta \]You need to login to perform this action.
