How to use the Math.atan2() function to get the arctangent of the quotient of its arguments in JavaScript

Answer 1

document.write("Math.atan2(1, 1) = " + Math.atan2(1, 1) + "<br />");
document.write("Math.atan2(1, -1) = " + Math.atan2(1, -1) + "<br />");
document.write("Math.atan2(-1, 1) = " + Math.atan2(-1, 1) + "<br />");
document.write("Math.atan2(-1, -1) = " + Math.atan2(-1, -1) + "<br />");
document.write("Math.atan2(90, 15) = " + Math.atan2(90, 15) + "<br />");
document.write("Math.atan2(15, 90) = " + Math.atan2(15, 90) + "<br />");
document.write("Math.atan2(0, -0) = " + Math.atan2(0, -0) + "<br />");
document.write("Math.atan2(0, 0) = " + Math.atan2(0, 0) + "<br />");
document.write("Math.atan2(Infinity, -Infinity) = " + Math.atan2(Infinity, -Infinity) + "<br />");
