Function Details : y1

doubley1(double x) ;

Return Type : double

Double-precision floating point (±1.7E±308, ~15 decimal digits)
Read about return values of y1 function .

1st Parameter Type : double

Double-precision floating point (±1.7E±308, ~15 decimal digits)

1st Parameter

The input value for which the Bessel function of the second kind of order 1 is to be computed. Must be positive.

The y1function in C language Calculates the Bessel function of the second kind of order 1 for the given value.
y1 computes the Bessel function of the second kind of order 1 for the input x. These special functions are solutions to Bessel's differential equation and are important in various areas of physics and engineering, particularly in problems involving cylindrical or spherical symmetry.
The y1function takes 1 parameter:
  • •
    double `x`: The input value for which the Bessel function of the second kind of order 1 is to be computed. Must be positive.
Computes the Bessel function of the second kind of order 1, denoted as `Y1(x)`. Returns the computed value. If `x <= 0`, the behavior is undefined, and an error may be returned.
The y1 function return value :
  • Returns the Bessel function of the second kind of order 1 for x
  • If x is negative, a domain error occurs and -HUGE_VAL is returned
  • If x is 0, a range error occurs and -HUGE_VAL is returned

Output

This example demonstrates the basic usage of y1 to compute the Bessel function of the second kind of order 1 for x = 1.0.
