Option three is correct one
Answer:
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.
Answer:
B
Step-by-step explanation:
Chords which intersect have segments whose products are equal. This means the chord with lengths 5 and x has a product 5x. It is equal to the the other chords lengths 5.1 and 9 as a product 5.1*9.
5x = (5.1)(9)
5x = 45.9
x = 9.18
9.18 rounds to the tenth place as 9.2
Answer:
(-4-5)0=1 because parentheses is raised to the zero power
or this becomes (-4[-5*0])=(-40)=1
or,...
