function doit() {
form.input.value = eval(form.input.value)
}
function Cos() {
x = form.input.value
if (x == ) alert( Error: Input Required )
else form.input.value = Math.cos(x)
}
function Sin() {
x = form.input.value
if (x == ) alert( Error: Input Required )
else form.input.value = Math.sin(x)
}
function Ln() {
x = form.input.value
if (x == ) alert( Error: Input Required )
