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