Application +4 | -1

\theta \in[0,2 \pi]

then number of ordererd pairs

(x, \theta)

which satisfies

x^4-2 x^2 \cos \theta+1=0

is/are

View answer and explanation

Correct option: D

Option D (4) is correct because the equation can be simplified to find the possible values of x and theta that satisfy it.
