## What is the difference between sin and sind in MATLAB?

1 Answer. From the documentation of sind : For integers n , **sind(n*180) is exactly zero, whereas sin(n*pi) reflects the accuracy of the floating point value of pi** .

**What does Sind mean in Matlab?**

Y = sind( X ) **returns the sine of the elements in X , which are expressed in degrees**.

**What is the sine function in Matlab?**

**Y = sin( X )** returns the sine of the elements of X . The sin function operates element-wise on arrays. The function accepts both real and complex inputs. For real values of X , sin(X) returns real values in the interval [-1, 1].

**Does sin in Matlab take radians or degrees?**

sin | Sine of argument in radians |
---|---|

sind | Sine of argument in degrees |

sinpi | Compute sin(X*pi) accurately |

asin | Inverse sine in radians |

asind | Inverse sine in degrees |

**What is the sin 90 degrees in Matlab?**

Matlab: sin(90) = **0.8940**.

**What is the difference between sin () and Sind () in MATLAB?**

1 Answer. From the documentation of sind : For integers n , **sind(n*180) is exactly zero, whereas sin(n*pi) reflects the accuracy of the floating point value of pi** .

**How do you write sin and cos in MATLAB?**

**Sine Function**

- Syntax: sin(value)
- Syntax: sind(value)
- Syntax: asin(x)
- Syntax: asind(x)
- Syntax: sinh(x)
- Syntax: asinh(x)
- Syntax: cos(value) where value is the input value.
- Syntax: cosd(value)

**What are the units of sin in Matlab?**

sin numerically evaluates these units automatically: **radian , degree , arcmin , arcsec , and revolution** .

**What is the argument of the sine function?**

The argument of the sine function is **by definition an angle**. We refer to this angle as the phase of the wave, ϕ=kx−ωt. The difference in the phase of a wave at fixed time over a distance of one wavelength is 2π, as is the difference in phase at fixed position over a time interval of one wave period.

**Is math sin degrees or radians?**

The sine is equal to the ratio of the side opposite the angle and the hypotenuse of the right-angled triangle they define. **The angle must be measured in radians**.

## What is sin equal to in radians?

The value of sin 1 is **0.8414709848**, in radian. In trigonometry, the complete trigonometric functions and formulas are based on three primary ratios, i.e., sine, cosine, and tangent in trigonometry.

**Does sin give radians?**

The function f(x) = sin x has all real numbers in its domain, but its range is −1 ≤ sin x ≤ 1. The values of the sine function are different, depending on whether the angle is in degrees or radians. **The function is periodic with periodicity 360 degrees or 2π radians**.

**What is the degree function in Matlab?**

**D = degree( G )** returns the degree of each node in graph G . The degree is the number of edges connected to each node. D = degree( G , nodeIDs ) returns the degree of the nodes specified by nodeIDs .

**How do you convert degrees to radians?**

To convert from degrees to radians, **multiply the number of degrees by π/180**. This will give you the measurement in radians. If you have an angle that's 90 degrees, and you want to know what it is in radians, you multiply 90 by π/180.

**What is the difference of sine?**

The difference formula for sines states that the sine of the difference of two angles equals the product of the sine of the first angle and cosine of the second angle minus the product of the cosine of the first angle and the sine of the second angle.

**What is the difference between sin and sinx?**

As an example, **sin expects an angle in radians while sind expects an angle in degrees**.

**What is value of sin 90?**

The exact value of sin 90 degrees is **1**.

**How do you find sin 2 in Matlab?**

**Direct link to this answer**

- x=0:0.01:2*pi;
- si=sin(x).^2;
- co=cos(x).^2;
- plot(x,si,x,co);
- figure;
- plot(si,co);%not sure which one you want.

**How do you write sin theta in Matlab?**

**y = sin( theta )** returns the sine of fi input theta using a lookup table algorithm.

**What is the difference between Cosd and Cos in Matlab?**

cosd (MATLAB Functions) Y = cosd(X) is the cosine of the elements of X , expressed in degrees. **For odd integers n , cosd(n*90) is exactly zero, whereas cos(n*pi/2) reflects the accuracy of the floating point value of pi** .

## How do you write cos in Matlab?

**Y = cos( X )** returns the cosine for each element of X . The cos function operates element-wise on arrays.

**Why does sine rule have two answers?**

Using the law of sines to find an unknown length can give rise to an ambiguous answer **due to the possibility of two solutions** (namely, when you are given two side lengths and a nonincluded, acute angle). If angle 𝐴 is acute and ℎ < 𝑎 < 𝑏 , two possible triangles, 𝐴 𝐶 𝑀 and 𝐴 𝐶 𝐵 , exist.

**What are sine values?**

The sine of an angle can be defined as **the ratio of the length of the perpendicular to the length of the hypotenuse in a right-angled triangle**. It gives the value of the sine function of the angle between the base and hypotenuse of the right triangle.

**Why is it called sine?**

In trigonometry, the name “sine” **comes through Latin from a Sanskrit word meaning “chord”**. In the picture of a unit circle below, AB has length sinθ and this is half a chord of the circle. The co-functions are functions of complementary angles: cosθ = sin(π/2 − θ), cotθ = tan(π/2 − θ), and cscθ = sec(π/2 − θ).

**What type of equation is sin?**

Sin and Cos are **basic trigonometric functions** along with tan function, in trigonometry. The sine of an angle is equal to the ratio of the opposite side to the hypotenuse whereas the cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

**How to do entropy in MATLAB?**

**Direct link to this answer**

- ent = entropy(uint8(str))
- ent = ComputeEntropy(str);
- p = sum(str. '==unique(str))./length(str); ent = -sum(p.*log2(p));
- ent = 3.6901.

**How to use s in MATLAB?**

Use S-Functions in Models. To incorporate a C MEX S-function in a model, **drag a S-function block from the Simulink Library Browser**. Similarly, to incorporate a Level-2 MATLAB S-function to the model, drag a Level-2 MATLAB S-function block to the model.

**How do you create a sine signal in MATLAB?**

**sine = dsp.** **SineWave(amp,freq,phase, Name,Value )** creates a sine wave object with the Amplitude property set to amp , Frequency property set to freq , PhaseOffset property set to phase , and anyother specified properties set to the specified values.

**How to use arcsin in MATLAB?**

**asin( X )** returns the inverse sine function (arcsine function) of X . All angles are in radians. For real values of X in the interval [-1,1] , asin(X) returns the values in the interval [-pi/2,pi/2] .
