A) \[\frac{1}{2}\]
B) \[0\]
C) \[-1\]
D) \[2\]
Correct Answer: B
Solution :
\[\sin \theta +\cos \theta =\sqrt{2}\cos ({{90}^{o}}-\theta )\] \[\sin \theta +\cos \theta =\sqrt{2}\sin \theta \] \[\Rightarrow \] \[\cos \theta =(\sqrt{2}-1)\sin \theta \] \[\Rightarrow \] \[\cot \theta =\sqrt{2}-1\]You need to login to perform this action.
