Answer:
First of all you need to know the it's equal to 2 and
which is the number is between 1 and 2 and between that number there maybe the possibilities of above 0.5 or under 0.5
After that Figure out which one was bigger? or
? The answer is
and
also near to
so it should be above 0.5 .
So we know that is between 1 and 1.5.
Hopes that information was help you a lot
Answer:
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Begin with the right hand side:
R.H.S = cot θ =
L.H.S = sin θ cos θ
so, sin θ cos θ ≠
So, the equation is not a trigonometric identity.

<u>Anther solution:</u>
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Assume θ with a value and substitute with it.
Let θ = 45°
So, L.H.S = sin θ cos θ = sin 45° cos 45° = (1/√2) * (1/√2) = 1/2
R.H.S = cot θ = cot 45 = 1
So, L.H.S ≠ R.H.S
So, sin θ cos θ = cot θ is not a trigonometric identity.
