| Directions: Each of these questions contains two statements: Assertion [A] and Reason [R]. Each of these questions also has four alternative choices, any one of which is the correct answer. You have to select one of the codes [a], [b], [c] and [d] given below. |
| Assertion \[\frac{\left( \sin \theta -\cos \theta \right)\left( \sin \theta +\cos \theta \right)}{\left( \cos \theta -\sin \theta \right)\left( \cos \theta +\sin \theta \right)}=-1\] |
| Reason \[{{\sin }^{2}}\theta +{{\cos }^{2}}\theta =-1\] |
A) A is true, R is true; R is a correct explanation for A.
B) A is true, R is true; R is not a correct explanation for A.
C) A is true; R is false.
D) A is false; R is true.
Correct Answer: C
Solution :
| Assertion \[\frac{{{\sin }^{2}}\theta -{{\cos }^{2}}\theta }{{{\cos }^{2}}\theta -{{\sin }^{2}}\theta }=-1\] |
| Assertion is true and Reason is false. |
