Just puzzling me the Error shown on firebug console:

Uncaught TypeError: Object #<Object> has no method 'Sin'
Uncaught TypeError: Object #<Object> has no method 'Cos'

yet my code gives the value for Math.PI

I'm totaly confused, I can't figure out what i did wrong, any help is greatly appreciated.

My code:

function callCordinates(angle){
    console.log(Math.PI); // shows 3.14...
    console.log(Math.Cos(0)); // throws error. :(

    var x1 = 480 + 100 * Math.Cos(angle * (Math.PI / 180));
    var y1 = 155 + 100 * Math.Sin(angle * (Math.PI / 180));
}

not start tomcat with the option "Server modules without publishing"

I have a small problem when the server starts,it can not find the web.xml context file. (documentation watch)

Here is the exception :

它的Math.sin，所以改变

Math.Sin(angle * (Math.PI / 180));

至

Math.sin(angle * (Math.PI / 180));

和它的Math.cos，所以改变：

Math.Cos

至

Math.cos

使用Math.sin代替 Math.Sin

同样 Math.cos代替 Math.Cos

于 2013-10-22T09:08:01.823 回答

按照惯例，常量都是大写的，而 JS 中的函数是小写的。 Math.PI是一个常数，因为是Math.E，所以它们是大写的，而，，，，和sin其他是函数，所以它们是小写的。costan

在这种情况下，Math.Sin应该是Math.sin而且Math.Cos应该是Math.cos
