How do you convert sin cos to weight?

How do you convert sin cos to weight?

1. In trigonometry,
2. There is a formula to convert cos to sin.
3. Cos x = sin (90- x)
4. Cos (90-x)=sin x.
5. So, cos (wt+120) = sin (90 – (wt+120))
6. Or,cos (wt+120) = sin(90-wt-120)
7. Or,cos (wt+120) = sin (- wt-30)
8. Or,cos (wt+120) = -sin (wt+30)

How does Cos relate to sin?

Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse . No matter the size of the triangle, the values of sin(θ) and cos(θ) are the same for a given θ, as illustrated below.

What is WT in sine wave?

Compare: FOURIER ANALYSIS. The angular velocity w of the motion is defined in radians per second as the angle q moved through per unit time, and is related to the FREQUENCY f by the equation: w = 2pf. The displacement d, whose maximum is the AMPLITUDE A, may be expressed as: d = A sin q = A sin wt = A sin (2pft)

What is the value of sin 90 Theta?

1
The exact value of sin 90 degrees is equal to 1.

For what angle measurement must sine and cosine have the same value?

▫ The sine of an angle is equal to the cosine of its complementary angle, and the cosine of an angle is equal to the sine of its complementary angle. Why is sin 90 = 1?

Which acute angle are the sine of the angle and cosine of the angle equal?

In a right triangle, the sine of one acute angle, A, equals the cosine of the other acute angle, B. Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary.

How do you convert sine to cosine of an angle?

All triangles have 3 angles that add to 180 degrees. Therefore, if one angle is 90 degrees we can figure out Sin Theta = Cos (90 – Theta) and Cos Theta = Sin (90 – Theta).

How do you find the value of sin degrees?

To find the value of sin 30 degree, we will use the following formula, Sinϴ = Perpendicular Hypotenuse. Thus, the value of Sin 30 degree is equal to 12(half) or 0.5. Just like the way we derived the value of sin 30 degrees, we can derive the value of sin degrees like 0°, 30°, 45°, 60°, 90°,180°, 270° and 360°.

What is the formula for a sine wave?

Sine Wave. 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 value of sin 120 degrees?

By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2.
