The incorrect statement is
$\sin \theta = - \frac{1}{5}$
$\cos \theta = 1$
$\sec \theta = \frac{1}{2}$
$\tan \theta = 20$
Find the values of other five trigonometric functions if $\cot x=\frac{3}{4}, x$ lies in third quadrant.
If $\tan \,(A - B) = 1,\,\,\,\sec \,(A + B) = \frac{2}{{\sqrt 3 }},$ then the smallest positive value of $B$ is
If $p = \frac{{2\sin \,\theta }}{{1 + \cos \theta + \sin \theta }}$, and $q = \frac{{\cos \theta }}{{1 + \sin \theta }},$ then
Which of the following is correct
If $\sin \theta + \cos \theta = m$ and $\sec \theta + {\rm{cosec}}\theta = n$, then $n(m + 1)(m - 1) = $
