Question

Hello I am trying to alter the sine cosine and tangent fucntion Math.sin Math.cos Math.tan so it can accept degrees How you alter them so it can accept a degree see my main fucnction I wrote the functions but I do not know how to alter the Math fucntions

var sin = function() {
if (arguments[1] == "d") {
arguments[0] = arguments[0] * Math.PI / 180;
}

return (Math.sin(arguments[0]));
};

var cos = function() {
if (arguments[1] == "d") {
arguments[0] = arguments[0] * Math.PI / 180;
}

return (Math.cos(arguments[0]));
};

var tan = function() {
if (arguments[1] == "d") {
arguments[0] = arguments[0] * Math.PI / 180;
}

return (Math.tan(arguments[0]));
};

Math.sin = function(angle, degree) { //it fails
sin(angle, degree);
};
(function() {
var angle;

while (angle = parseFloat(readline())) {
print(Math.sin(angle, "d").toPrecision(5)); // degrees
print(Math.sin(angle).toPrecision(5)); // radians
print(Math.cos(angle, "d").toPrecision(5));
print(Math.cos(angle).toPrecision(5));
print(Math.tan(angle, "d").toPrecision(5));
print(Math.tan(angle).toPrecision(5));
}
})();

Explanation / Answer

Multiply the result by 180/Math.PI to convert from radians to degrees.

You could also define your own functions:

and so on.
