Summarizing the correlation function of sine in C language _c language

C language Sin () function: sine function
header file:

#include <math.h>

The sin () function is used to find the sine value of a given value, and its prototype is:

 Double sin (double x);

The value given by the parameter (radians).

Return value returns the calculated result from 1 through 1.

The relationship between radians and angles is:
radians = 180/π angle
Angle =π/180 radians

Use the Rtod () function to convert radian values to angle values.

Note that when compiling with GCC, please join-LM.

Examples are as follows:

#include <stdio.h>
#include <math.h>
int main ()
{
 printf ("7 ^ 3 =%f\n", pow (7.0, 3.0)); 
   printf ("4.73 ^ =%f\n", pow (4.73, 12.0));
  printf ("32.01 ^ 1.54 =%f\n", pow (32.01, 1.54));
  return 0;
}

Output results:

7 ^ 3 = 343.000000
4.73 ^ a = 125410439.217423
32.01 ^ 1.54 = 208.036691

C language Sinh () function: hyperbolic positive and metaphysical functions
header file:

 #include <math.h>

Sinh () is used to find hyperbolic sine, whose prototype is:

 Double Sinh (double x);

"Parameter" x is the value that is about to be computed.

The hyperbolic sine is defined as: (exp (x)-exp (-X))/2, i.e.

The hyperbola diagram is as follows:

Return value returns the hyperbolic positive value of the parameter x.

If the return value is too large, it returns HUGE_VAL, or Huge_valf, or huge_vall, with the same sign and X, causing a range overflow error and setting the global variable errno to Erange.

Note that when compiling with GCC, please join-LM.

Take a look at the following code:

#include <math.h>
Main () {
 Double answer = sinh (0.5);
 printf ("sinh (0.5) =%f\n", answer);
}

Output results:

Sinh (0.5) = 0.521095

C Language ASIN () function: The value of the inverse string (in radians)
header file:

#include <math.h>

To define a function:

Double asin (Double x)

Function Description: ASIN () is used to compute the inverse chord value of the parameter x, and then returns the result. The parameter x range is between 1 and 1 and will fail if it exceeds this range.

Return value: Returns the result of the calculation between the PI/2 of the-PI/2.

Error code: EDOM parameter x is out of range.

Note that when compiling with GCC, please join-LM.

Example

#include <math.h>
Main () {
 double angle;
 Angle = ASIN (0.5);
 printf ("angle =%f\n", angle);
}

Perform

Angle = 0.523599
