sinh function

dynamic sinh(dynamic x)

Returns the hyperbolic sine of a number.

Example 1:

print(sinh(1));  // Output: 1.1752011936438014

Example 2:

print(sinh(Complex(1, 2))); // Output: -0.4890562590412937 + 1.4031192506220405i

Example 3:

print(sinh(Matrix.identity(2))); // Output: [[1.0, 0.0], [0.0, 1.0]]

Implementation

dynamic sinh(dynamic x) {
  if (x is num) {
    return (exp(x) - exp(-x)) / 2;
  } else if (x is Complex) {
    return x.sinh();
  } else if (x is Matrix) {
    return MatrixFunctions(x).sinh();
  } else {
    throw ArgumentError('Input should be either num or Complex');
  }
}
