The solution set is{} (Use a comma to separate answers as needed Type an exadt answer. using x as needed use integers or fractions tor any numbers in he expression ) A. x as needed Use integers or fractions for any numbers in the express 0 B. There is no solution. Click to select and enter your answer(s)
Solution
sec^2 theta + tan theta = 0
sec^2 theta = 1 + tan^2 theta
so equation becomes
1 + tan^2 theta + tan theta = 0
tan theta =( -1 + i sqrt 3 ) / 2 , ( -1 - i sqrt 3 ) /2
therefore ,
the equation has no solutions
2nd option is correct
