A) 1
B) 2
C) 3
D) 4
Correct Answer: C
Solution :
[c] \[\cos ec\theta -\cot \theta =\frac{1}{3}\] |
Also,\[\cos e{{c}^{2}}\theta -{{\cot }^{2}}\theta =1\] |
\[\Rightarrow \,\,\,\,\,\,\,(\cos ec\,\,\theta +\cot \theta )\,\,(\cos ec\,\theta -\cot \theta )=1\] |
\[\Rightarrow \,\,\,\,\,\,\,(\cos ec\,\,\theta +\cot \theta )\,\,\times \frac{1}{3}=1\] |
\[\Rightarrow \,\,\,\,\,\,\,\cos ec\,\,\theta +\cot \theta =3\] |
