A) 1
B) 0
C) ? 1
D) ? 2
Correct Answer: B
Solution :
(b): \[\sin \theta \cos \theta -\frac{\sin \theta .\sin \theta \cos \theta }{\cos ec\theta }-\frac{\cos \theta .\cos \theta \sin \theta }{\sec \theta }\] \[=\sin \theta cos\theta -sin\theta cos\theta \left[ {{\sin }^{2}}\theta +{{\cos }^{2}}\theta \right]\] \[=\sin \theta \cos \theta -\sin \theta \cos \theta =0\]You need to login to perform this action.
