Which of the following is/are incorrect ?
(A) $\sin 0^{\circ}=0$
(B) $\tan 0^{\circ}=0$
(C) $\cos 0^{\circ}=0$
(D) $cosec ~0^{\circ}=0$
(E) $\sec 0^{\circ}=0$
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
(A) $\sin 0^{\circ}=0$
(B) $\tan 0^{\circ}=0$
(C) $\cos 0^{\circ}=0$
(D) $cosec ~0^{\circ}=0$
(E) $\sec 0^{\circ}=0$
we know that,
$\sin 0^{\circ}=0$
$\tan 0^{\circ}=0$
$\cos 0^{\circ}=0$
Among all of them, only c, d, and e are incorrect others are correct.
The correct answer is Option (4) → (C), (D) and (E) only
