A) Infinite
B) 1
C) 2
D) 0
Correct Answer: D
Solution :
\[8{{\sec }^{2}}\theta -6\sec \theta +1=0\]Þ \[\sec \theta =\frac{1}{2}\] or \[\sec \theta =\frac{1}{4}\] , but \[\sec \theta \ge 1\ \text{or}\ \sec \theta \le -1\]. Hence the given equation has no solution.You need to login to perform this action.
