## What ratio describes the cosine function?

Cosine ratios, along with sine and tangent ratios, are ratios of two different sides of a right triangle. Cosine ratios are specifically the ratio of the side adjacent to the represented base angle over the hypotenuse. In order to find the measure of the angle, we must understand inverse trigonometric functions.

## Which of the following ratios correctly describes the target function?

thus, opp/adj correctly describes the tangent function.

## Which statement does not describe the cosine function Brainly?

Answer: The correct answer is: The cycle repeats every 2π radians.

12

## What is the equation of the sinusoid?

Consider one of the most common waveforms, the sinusoid. A general form of a sinusoidal wave is y(x,t)=Asin(kx−ωt+ϕ) y ( x , t ) = A sin ( kx − ω t + ϕ ) , where A is the amplitude of the wave, ω is the wave’s angular frequency, k is the wavenumber, and ϕ is the phase of the sine wave given in radians.

## How do you find the maximum and minimum of a cosine function?

The maximum value of the function is M = A + |B|. This maximum value occurs whenever sin x = 1 or cos x = 1. The minimum value of the function is m = A ‐ |B|. This minimum occurs whenever sin x = −1 or cos x = −1.

## How do you find the maximum and minimum of a midline?

midline = 1 2 (max + min) = 1 2 (40 + (-20)) = 10. The amplitude is half the distance between the max and the min, so amplitude = 1 2 (max – min) = 1 2 (40 – (-20)) = 30.

## What is the minimum value of cos?

The minimum value of cos(cosx)is cos1. Note: Cosine is a decreasing function. It has maximum value 1 when x=0∘ and minimum value 0 when x=π2.

## What is maximum value of cos A?

Properties Of The Cosine Graph Maximum value of cos θ is 1 when θ = 0 ˚, 360˚. Minimum value of cos θ is –1 when θ = 180 ˚. So, the range of values of cos θ is – 1 ≤ cos θ ≤ 1.

## What is minimum value of Sina 0 A 90?

As sin 90 is equal to zero.

## What is the maximum value of 1 Cos A?

1/cosecA means sin therefore the maximum value is sin is 1 .

## What is the formula of 1 cos2x?

Therefore, 1 + cos2x = 2cos^2(x)…….

## What is the maximum value of 1 by SEC Theta?

The maximum value of 1/sec θ is the maximum value of cos θ. The maximum value of cos θ is 1. The value of cos θ lies between – 1 & 1.

## What is the maximum value of 2 Cosec Theta?

Answer. i.e maximum value of 2/cosec A is 2.

## What is the minimum and maximum value of sec theta?

Answer. Answer: At θ = π/2 +ε , sec(θ) = -Infinity; At θ = π , sec(θ) = – 1; At θ = 3π/2 -ε, sec(θ) = -Infinity; Note2: In this interval sec(θ) has a minimum of -Infinity , and a max of -1.

## What is maximum value of 3 upon Cosec Theta?

Answer: Step-by-step explanation: 3 / cosec x = 3 sin x <= 3. the maximum value is therefore 3.

## What is the maximum value of 1 Cosec θ?

1/cosec​θ=sinθ. 1/cosecθ has a maximum value of 1.

## What is the maximum value of justify your answer?

justify your answer. the maximum malue of cosec theta is infinite .

## What is the maximum value of 1 Cosecθ justify your answer?

1/ cosecθ = Sinθ. It’s maximum value is 1.

## What is the minimum value of Cosec Theta?

minimum value of cosecθ tends to -∞ but you know, cosecθ is undefined at 0°, 180°, 270°, so, in range of cosecθ isn’t included (-1, 1) values. because cosecθ will be undefined in this range.

## What is the maximum and minimum value of 1 by Cosec Theta?

Answer. 1/cosec​θ=sinθ. 1/cosecθ has a maximum value of 1.

## What is the maximum value of Cosec Theta?

Answer. Answer: Step-by-step explanation: Maximum value of cos θ is 1 when θ = 0 ˚, 360˚.

## What is the formula of 1 cos4x?

Answer. cos 4x = cos 2(2x)= 2cos^2(2x) – 1 ——(1) cos 4x = cos 2(2x) = 1- sin^2 (2x) ——(2) cos 4x = cos^2(2x) – sin^2 (2x) ———(3) again the above threeformulas can be written as simplified form using formula cos 2x = 2cos^2 x -1 / 1- 2sin^2 x / cos^2 x – sin^2 x as per requirement.
