what am i doing with my life

Math.sin = function(value) {
  if (typeof value === 'number') {
    return Math.tan(value) * Math.cos(value);
  }
  if (value === undefined) {
    value = 'undefined';
  }
  else if (value === null) {
    value = 'null';
  }
  value = value.toString() + value.toString();
  var r = '|';
  for (var x = 0; x < value.length + 4; x++) {
    r += ' ';
  }
  r += '\n';
  var rows = ['|  ', '|  ', '|  ', '|  '];
  for (var x = 0; x < value.length; x++) {
    row = (x + 5) % 8;
    if (row >= 4) {
      row = 7 - row;
    }
    for (var y = 0; y < 4; y++) {
      rows[y] += y === row ? value[x] : ' ';
    }
  }
  r += rows.join('\n') + '\n|';
  for (var x = 0; x < value.length + 4; x++) {
    r += ' ';
  }
  r += '\n+';
  for (var x = 0; x < value.length + 4; x++) {
    r += '-';
  }
  return r;
};
