prove that sin theta cos theta = cot theta is not a trigonometric identity by producing a counterexample
Zolol [24]

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 = \frac{cos \ \theta}{sin \ \theta}

L.H.S = sin θ cos θ

so, sin θ cos θ ≠ \frac{cos \ \theta}{sin \ \theta}

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.

PLEASE HELP !!!!!!!! WILL MARK BRAINLIEST IF CAN!
Margaret [11]

Answer:

The answer is A. You just have to plug in.

Step-by-step explanation:

5x - y/3= 13

(2,-9) and (3,-6)

5(2) - -9/3 = 13

10 + 3 = 13

13 = 13 (true)

5(3) - -6/3= 13

15+ 2 = 13

17 = 13 (wrong)

HELP What is the area of a circle with a radius of 13 feet? IT IS NOT 530.93 ft ​
NeTakaya

Answer:

530.66

Step-by-step explanation:

to find the area you need to do pi times the radius square and to find the radius squared you just times it by its self so 13 times 13 which is 169 and pi is 3.14

so now you just do 3.14x169=530.66
