If sec(t) = , then cot(t) is equal to:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. .
sec(t) =
⇒ sec(t) = 1/cos(t)
⇒ cos(t) =
We know that,
⇒ sin2(t) + cos2(t) = 1
⇒ sin2(t) + ()2 = 1
⇒ sin2(t) = 1 - ()2
⇒ sin2(t) = ()
⇒ sin(t) =
Now,
⇒ cot(t) = cos(t)/sin(t)
⇒ cot(t) = /
⇒ cot(t) =
