Feather painting by action Code: OnMouseDown = init; function init () {// create a feather, and set each feather parameter and call the function feather = createEmptyMovieClip ("f" + I, 10000 + I ++); feather. swapDepths (Math. random () * 10000);

Sin cos exp is calculated using the Taylor Formula and mclawin formula. To prevent the power operation index from being too high, it is easy to cause overflow when a large input parameter is calculated. Considering that sin and cos both use 2 * PI

Js math atan2 cos sin 1. Give the relative coordinate center o, p1 to o distance l, p1 to X axis angle (0 ~ 2PI) left：x0+Math.cos(angle)top: y0+Math.sin(angle) 2. The relative coordinate center o and p1 coordinates are given, and the angle between

I've been trying to write an article for a long time and talk to you:\frac{1}{1^2}+\frac{1}{2^2} +\frac{1}{3^2} +\frac{1}{4^2} +\frac{1}{5^2} +\cdots\ =\ \frac{π^2}{6}But there has been no chance, this summer vacation just have free, so the hand

The Math object is different from the above object. It can be said to be a common mathematics class, which has many mathematical methods used for various mathematical operations, but Math objects do not need to be constructed, you can directly use

1. Coordinate system:Flash coordinate system and mathematical coordinate system: the X axis is the same, and the y axis is the opposite.[Mathematical coordinate system][Coordinate system in Flash]2. Conversion between Angle and Radian:(1) radians:

Recently, we have been working on this coordinate transformation task, which involves many profound things such as surveyors. Here I will not explain these difficult theories. Here, I will post the code to share with you. In fact, if you want to

In flash, the math class is a very common class. Through mathematical computation, we can achieve a lot of wonderful results. Here we will start from the most basic learning and add a math knowledge. Let's take a look at the math class provided in

Study Notes of the Random and Math modules in Python This article mainly introduces the study notes of the Random and Math modules in Python. This article describes the mathematical constants, common simple functions, and trigonometric functions of
