what does the sine function do in matlab Sine cosine and related functions with results in radians or degrees The trigonometric functions in MATLAB calculate standard trigonometric values in radians or degrees hyperbolic trigonometric values in radians and inverse variants of each function
Sine Function for Numeric and Symbolic Arguments Depending on its arguments sin returns floating point or exact symbolic results Compute the sine function for these numbers Because these numbers are not symbolic objects sin returns floating point results A sin 2 pi pi 6 5 pi 7 11 A Description The sin function operates element wise on arrays The function s domains and ranges include complex values All angles are in radians Y sin X returns the circular sine of the elements of X Examples Graph the sine function over the domain x pi 0 01 pi plot x sin x grid on

Sine Function sin Sin function returns the sine of input in radians The input can be a number or an array or a matrix Syntax sin value sind This function returns the sine of input in degrees Syntax sind value asin This function returns the inverse of sine in radians Syntax asin x In MATLAB the sin and sind function is used to find the sine of a given argument The sin function returns the sine of a value in radians and the sind function returns the sine of a value in degrees
This article discussed how to use built in inline functions of MATLAB and how to define inline functions in a MATLAB script We also discuss all the various options that could be used with user defined inline functions and how to call those functions with various parameters Accepted Answer Steven Lord Since it is a built in function there is little information provided and many online Q A s have to do with using the sine function for particular applications not the fundamental code level evaluation of the function
