Let O(0, 0) and P(x, y) be a point on the unit circle. The cosine of the angle between the positive x-axis and OP is x, the abscissa of P. What is the unit circle in trigonometry? In trigonometry, the unit circle is a circle of radius 1 centered at the origin, that is, ...

Sine and cosine live on the unit circle (radius 1). The other functions use a radius of secant (tan/sec) or cosecant (cot/csc).Q3: What's the swapped function?We make a mini-triangle by shrinking the original triangle down, and rotating so dx matches the side of length 1. It ...
Well, if you look at the 180o angle on the circle, it intersects at the point (-1,0). So cos 180o = -1 and sin 180o = 0. When you get used to this, it can be a great time saver and boost your intuitive feel for the trig functions enormously. As a small test for ...
console.log("The area of a circle of radius 4 is " + circle.area(4)); 编写稍大一点的程序时一般都会将代码模块化。在NodeJS中,一般将代码合理拆分到不同的JS文件中,每一个文件就是一个模块,而文件路径就是模块名。 在编写每个模块时,都有require、exports、module三个预先定义好的变量可供使用。

var aCircle = new Circle(5, 11, 99); 使用构造器函数的优点是,它可以根据参数来构造不同的对象。 缺点是构造时每个实例对象都会生成重复调用对象的方法,造成了内存的浪费。 function Test(name){ this.occupation = "coder"; this.name = name; this.whoAreYou = function(){ return "I'm " + ...
