Sine and cosine wave between two arbitrary values

sineandcosinebetween.js

function sineBetween(min, max, t)
{
    var halfRange = (max - min) / 2;
    return min + halfRange + Math.sin(t) * halfRange;
}

function cosineBetween(min, max, t)
{
    var halfRange = (max - min) / 2;
    return min + halfRange + Math.cos(t) * halfRange;
}
