function

[admin]

}

i'm not so sure if this is corrrect,
cause there's seems to be an error.



function calculate2() {
with (document.num) {
y.value= Number(0.5) * Number(d.value) * 1/Math.tan(x)* Number(a.value);
}
}

the formula that i'm suppose to use is
y=0.5 D cot a
--------------------------------------------------------------------
i have try editing the function:
function calculate2() {
with (document.num) {
y.value= 0.5 * d.value * (1/Math.tan(x.value));
}
}

it does work but then the problem is they the output is totally wrong
for example:
0.5* 5*1/tan30=4.33012
but the output is -0.39029988040414803.
