Question

If $\Rightarrow$and $\tan^{3}x + \tan^{2}x - \tan x - 1 = 0$, then the general value of $\Rightarrow$is .

• A. $(\tan^{2}x - 1)(\tan x + 1) = 0$
• B. $\Rightarrow$
• C. $x = m\pi \pm \frac{\pi}{4}$
• D. $n = 0$

Answer 1

Answer: (B)

$\Rightarrow$

Answer 2

$\sin\lambda + \cos p\lambda = 1$; $- \sin\lambda + \cos p\lambda = 1$

$\sin\lambda = 0$ The general value is $\lambda = n\pi$ or $\cos p\lambda = 1$.
