Solve $\cos x=\frac{1}{2}$
We have, $\cos x=\frac{1}{2}=\cos \frac{\pi}{3}$
Therefore $\quad x=2 n \pi \pm \frac{\pi}{3},$ where $n \in Z$
If $tanA + cotA = 4$, then $tan^4A + cot^4A$ is equal to
The value of $\theta $ in between ${0^o}$ and ${360^o}$ and satisfying the equation $\tan \theta + \frac{1}{{\sqrt 3 }} = 0$ is equal to
The number of all possible triplets $(a_1 , a_2 , a_3)$ such that $a_1+ a_2 \,cos \, 2x + a_3 \, sin^2 x = 0$ for all $x$ is
The smallest positive values of $x$ and $y$ which satisfy $\tan (x – y) = 1,\,$ $\sec (x + y) = \frac{2}{{\sqrt 3 }}$ are
