Skrip tersebut disimpan dengan file berekstensi jenis HTML (*.html)

3. berapa jumlah variabel yang didefinisikan dalam file tersebut !
Jumlan variabelnya ada 11.

4. Berapa jumlah fungsi yang ada didalam skrip tersebut !
Jumlah fungsinya ada 11.

5. Tuliskan nama semua variabel skrip javascript tersebut ?
var plussign = ' + ';
var minussign = ' - ';
var multiplysign = ' * ';
var dividesign = ' / ';
var decimalsign = ' . ';
var negativesign = ' -';
var leftbracket = ' (';
var rightbracket = ') ';
var rad = 3.141592654 / 180;
var base_10 = Math.LN10;
var base_2 = Math.LN10;

6. Tuliskan nama semua fungsi skrip tersebut ?

function base2_log(form)

7. Tuliskan skrip untuk membuat tampilan display pada skrip tersebut !

<input type="text" name="expr" size="35"
action="calculate(this.form)">

8. Tuliskan skrip untuk membuat 1 tombol !
<input type="button" value=" sin " Onclick="sin_form(this.form)">

9. Tuliskan fungsi jika tombol = ditekan oleh mouse !
<input type="button" value=" = " onClick="calculate(this.form)">

10. Tuliskan skrip untuk membersihkan display !
<input type="button" value=" C " onClick="clear_display(this.form)">
