    document.getElementById('ex').innerHTML = "e" + "<sup>x</sup>";
    document.getElementById('frac').innerHTML = "Frac";
    document.getElementById('sin').innerHTML = "sin" + "<sup>-1</sup>";
    document.getElementById('pi').innerHTML = "2π"; ...
  } else {
    document.getElementById('inv').style.backgroundColor = "#cccccc";
    document.getElementById('ex').innerHTML = "ln";
    document.getElementById('frac').innerHTML = "Int";
    document.getElementById('sin').innerHTML = "sin";
