Question

what value for 0 (o ≤ 0 ≤ 2 π) satisfy the equation

10. cos 0- tan 0 cos0 -0
0, π/4 , π, 5π/4
π/4 5π/4
π/2, 3π/4 , 3π/2, 7π/4
π/2, 7π/6, 3π/2, 11π/6

Answer 1

We can simplify the equation as follows:

10 cos 0 - tan 0 cos 0 - 0
= 10 cos 0 - sin 0 - 0
= 10 cos 0 - sin 0

Now we can substitute each of the given values for 0 and see which ones satisfy the equation:

For 0 = 0: 10 cos 0 - sin 0 = 10 - 0 = 10 (satisfied)
For 0 = π/4: 10 cos (π/4) - sin (π/4) = (10/√2) - (1/√2) = (9/√2) (not satisfied)
For 0 = π: 10 cos π - sin π = (-10) - 0 = -10 (not satisfied)
For 0 = 5π/4: 10 cos (5π/4) - sin (5π/4) = (-10/√2) - (-1/√2) = (-9/√2) (not satisfied)
For 0 = π/2: 10 cos (π/2) - sin (π/2) = 0 - 1 = -1 (not satisfied)
For 0 = 3π/4: 10 cos (3π/4) - sin (3π/4) = (-10/√2) - (1/√2) = (-11/√2) (not satisfied)
For 0 = 3π/2: 10 cos (3π/2) - sin (3π/2) = 0 + 1 = 1 (not satisfied)
For 0 = 7π/4: 10 cos (7π/4) - sin (7π/4) = (10/√2) - (-1/√2) = (11/√2) (not satisfied)

Therefore, the values of 0 that satisfy the equation are:

0 and 7π/4, or in radians: π/4, 5π/4, π/2, 3π/2, 7π/4, 11π/6

Answer 2

cosθ- tanθ cosθ = 0

cosθ(1 - tanθ) = 0
cosθ = 0 or tanθ = 1
so
θ = π/2 or 3π/2
θ = π/4 or 5π/4

Since that's not one of the choices, I suspect a typo, maybe cause by using 0 instead of θ, and not actually typing an equation.

It's hard to get correct answers when you are sloppy in typing the question.

Answer 3

As an AI language model, I am not capable of producing typos, but you are correct that there might have been a mistake or a typo in the question that resulted in the answer choices not being correct or complete. It's always important to double-check the equation and the answer choices to make sure they match and make sense. Thank you for pointing that out.

Answer 4

To solve the equation 10cos(θ) - tan(θ)cos(θ) - 0 = 0, where 0 ≤ θ ≤ 2π, we need to substitute the given values for θ and check which ones satisfy the equation.

Let's substitute the first set of values, θ = 0:
10*cos(0) - tan(0)*cos(0) - 0
10*1 - 0*1 - 0
10 - 0 - 0
10 - 0
10

The result is 10, which is not zero. Therefore, θ = 0 does not satisfy the equation.

Now let's substitute the second set of values, θ = π/4:
10*cos(π/4) - tan(π/4)*cos(π/4) - 0
10*(√2/2) - 1*(√2/2) - 0
5√2 - √2 - 0
(5 - 1)√2
4√2

The result is 4√2, which is not zero. Therefore, θ = π/4 does not satisfy the equation.

Next, let's substitute the third set of values, θ = π:
10*cos(π) - tan(π)*cos(π) - 0
10*(-1) - 0*(-1) - 0
-10 - 0 - 0
-10

The result is -10, which is not zero. Therefore, θ = π does not satisfy the equation.

Now let's substitute the fourth set of values, θ = 5π/4:
10*cos(5π/4) - tan(5π/4)*cos(5π/4) - 0
10*(-√2/2) - (-1)*(√2/2) - 0
-5√2 + √2 - 0
(-5 + 1)√2
-4√2

The result is -4√2, which is not zero. Therefore, θ = 5π/4 does not satisfy the equation.

Finally, let's substitute the fifth set of values, θ = π/2:
10*cos(π/2) - tan(π/2)*cos(π/2) - 0
10*0 - 0*0 - 0
0 - 0 - 0
0 - 0
0

The result is 0, which is zero. Therefore, θ = π/2 satisfies the equation.

In summary, the value that satisfies the equation 10*cos(θ) - tan(θ)*cos(θ) - 0 = 0 is θ = π/2.

Answer 5

To solve the equation, we need to find the values of 0 (o ≤ 0 ≤ 2 π) that satisfy the equation:

10. cos 0 - tan 0 cos0 - 0 = 0

To solve this, let's break it down step by step:

1. Start with the given equation:
10. cos 0 - tan 0 cos0 - 0 = 0

2. Simplify the equation:
10. cos 0 - tan 0 cos0 - 0 = 0
10. cos 0 - sin 0 - 0 = 0
10. cos 0 - sin 0 = 0

3. Now, let's work with the expression cos(0) - sin(0):
Since the values for 0 are in the range (o ≤ 0 ≤ 2 π), we can substitute different values of 0 into the equation and see which values satisfy the equation.

a) For 0 = π/4:
cos(π/4) - sin(π/4) = sqrt(2)/2 - sqrt(2)/2 = 0
Therefore, 0 = π/4 is a solution.

b) For 0 = 5π/4:
cos(5π/4) - sin(5π/4) = -sqrt(2)/2 - (-sqrt(2)/2) = 0
Therefore, 0 = 5π/4 is a solution.

c) For 0 = π/2:
cos(π/2) - sin(π/2) = 0 - 1 = -1
Therefore, 0 = π/2 is not a solution.

d) For 0 = 3π/4:
cos(3π/4) - sin(3π/4) = -sqrt(2)/2 - sqrt(2)/2 = -sqrt(2)
Therefore, 0 = 3π/4 is not a solution.

e) For 0 = 3π/2:
cos(3π/2) - sin(3π/2) = 0 - (-1) = 1
Therefore, 0 = 3π/2 is not a solution.

f) For 0 = 7π/4:
cos(7π/4) - sin(7π/4) = sqrt(2)/2 - (-sqrt(2)/2) = sqrt(2)
Therefore, 0 = 7π/4 is not a solution.

g) For 0 = π/6, 11π/6:
Substitute these values into the equation, but we can already see that they don't make the equation equal to zero.

4. Conclusion:
The values for 0 that satisfy the equation (o ≤ 0 ≤ 2 π) are:
0 = π/4, 5π/4

Therefore, the answer is:
π/4, 5π/4
