MCQ
The incorrect statement is
  • A
    $\sin \theta = - \frac{1}{5}$
  • B
    $\cos \theta = 1$
  • $\sec \theta = \frac{1}{2}$
  • D
    $\tan \theta = 20$

Answer

Correct option: C.
$\sec \theta = \frac{1}{2}$
c
(c) Incorrect statement is $\sec \theta = \frac{1}{2}$, because value of $\sec \theta $ is always $ \ge 1$.
