Why do cosine to the negative 1th power and cosine cancel out each other?

Cosine to the negative first power and cosine cancel each other out because cosine to the negative first power is one over cosine, and one over anything times anything is just one.

What happens when a square root radical is raised to the second power?
they cancel each other out. the square root of 5 raised to the second power = 5
What happens when ninth root of a number is raised to the ninth power?
The power and the root cancel each other out and the result is the radicand (the number under the radical sign).
What is negative 5 to the power of negative 2 times negative 5 to the power of negative 2?
negative 0.0016
How do you calculate the negative power of a number?
A negative power. When something is to the power of negative two, say X it would be 1/X. If something is to the power of negative 3, it would be.... etc
What is negative 4 to the power of 2 times negative 4 to the power of negative 2?
1
What is cosine to the negative first power?
[ cos(Θ) ]-1 = 1/cosine(Θ) = secant(Θ)
Power factor is not greater than unity?
Yes. Power factor is never greater than one, nor less than negative one. It is the cosine of the phase angle, and is the ratio of true versus apparent power.A negative power factor can occur in the case of a generator.
Can be the power factor become negative reading?
Yes, power factor can be negative. That is the case of a generator. Power factor is the cosine of the phase angle between voltage and current, and the cosine can be positive or negative.AnswerNo. Power factor can be 'leading' or 'lagging', but it cannot be 'negative' or 'positive'.
What power could certain Roman officials use to stop or cancel actions of other officials?

What happens when a square root radical is raised to the second power?
they cancel each other out. the square root of 5 raised to the second power = 5
Can power factor greater than 1?
not possible. power factor is an cosine angle between current and voltage...
Why power factor expressed in cosine angle?
The vector-relationship between apparent power, true power, and reactive power is represented by a right-angled triangle, whose hypotenuse represents apparent power and whose adjacent represents true power. Since power factor is defined as 'the ratio of true power to apparent power', you will find that this ratio corresponds to the cosine of the angle between them.
Why it is power fector of cos?
Power factor is the ratio of the angle between the voltage and current.In the power triangle cosine angle is the ratio between them...
Why can't we connect the plus of one battery (or any power supply) to the negative of another battery without connecting both sources in series or parallel and get current flow, and why does it not work this way please?
If the batteries are incorrectly connected, the batteries will cancel out each other’s energy and quickly flatten each other
What happens when ninth root of a number is raised to the ninth power?
The power and the root cancel each other out and the result is the radicand (the number under the radical sign).
How can you find the power factor?
Power factor is the cosine of the phase angle between voltage and current. It is also KW/KVA.
What is negative 5 to the power of negative 2 times negative 5 to the power of negative 2?
