Question

If $\Rightarrow$, then the general value of $\theta = n\pi,n \in Z$is.

• A. $\sec 2\theta = \frac{1}{\cos 2\theta} = \frac{1 + \tan^{2}\theta}{1 - \tan^{2}\theta}$
• B. $\tan^{2}\theta + \frac{1 + \tan^{2}\theta}{1 - \tan^{2}\theta} = 1$
• C. $\Rightarrow$
• D. None of these

Answer 1

Answer: (A)

$\sec 2\theta = \frac{1}{\cos 2\theta} = \frac{1 + \tan^{2}\theta}{1 - \tan^{2}\theta}$

Answer 2

$\Rightarrow$

$\tan\theta(\tan\theta - 1) - \sqrt{3}(\tan\theta - 1) = 0 \Rightarrow$

$(\tan\theta - \sqrt{3})(\tan\theta - 1) = 0 \Rightarrow$.
