sine 180

Introduction to the formula of sin function Grammar: SIN (number) Number is the angle, in radians, that requires a sine. Note: If the unit of the parameter is degrees, you can multiply PI ()/180 or use the RADIANS function to convert it to

Long time no blog, recently in the study of WPF under the painting of bubbles, research and development process is more difficult (mainly to review the high school mathematics knowledge, MMP all forgot), this blog is mainly to provide a way for

Use SurfaceView to display the sine curve, simulate the oscilloscope, and surfaceview the sine.     As we all know, views are repainted through refresh. The Android system re-painted the screen by sending a VSYNC signal. The interval for refresh is 1

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);

C language Sin () function: sine functionheader file: #include The sin () function is used to find the sine value of a given value, and its prototype is: Double sin (double x); The value given by the parameter (radians).

Cosine curveOf course, we don't use arrays here ... Otherwise, there is no technical content.Sine curve is characterized by symmetry, and the left part of the ordinate is from 11 straight down to 1, the corresponding right of the ordinate is from 11
