The word "sine" (Latin "sinus") comes from a Latin mistranslation of the Arabic jiba, which is a transliteration of the Sanskrit word for half the chord, jya-ardha.
The function sine can be traced to the jyā and koṭi-jyā functions used in Gupta period Indian astronomy ( Aryabhatiya, Surya Siddhanta), via translation from Sanskrit to Arabic and then from Arabic to Latin. The function sine can be traced to the jyā and koṭi-jyā functions used in Gupta period Indian astronomy (Aryabhatiya, Surya Siddhanta), via translation from Sanskrit to Arabic and then from Arabic to Latin. The sine function is commonly used to model periodic phenomena such as sound and light waves, the position and velocity of harmonic oscillators, sunlight intensity and day length, and average temperature variations throughout the year.

More modern definitions express the sine as an infinite series or as the solution of certain differential equations, allowing their extension to arbitrary positive and negative values and even to complex numbers. More generally, the definition of sine (and other trigonometric functions) can be extended to any real value in terms of the length of a certain line segment in a unit circle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse). End of snip Second, You want to show 12 cycles in 360 degrees?Īnd be half as high? That means change the original snip to this new snip.In mathematics, the sine is a trigonometric function of an angle. int r = 30 * amp // amplitude // CHANGE THIS TO A DOUBLE NOTED IN THE NEXT LINE double r = 30 *amp. Begin of snip // int amp // CHANGE THIS TO A DOUBLE NOTED IN THE NEXT LINE double amp. For those changes from the original program above, these 2 variables go from 'int' to 'double'. For your requested change: First, Consider that we will only change the left most button to get the 'shapes' you want. If you are looking at an output from a piece of equipment then that is a different situation. Guster, I am extremely curious!!! What are you looking at that requires the adjusments that you want here? If you are working with equations from a math class then share the equations with me. G.dispose() You don't need to do that in the paint method because it is done for you, but you need it whenever you use getGraphics.

The System (Windows) has a limited number of Graphics and you need to dispose them to free System ressource DO: Graphics g = m圜anvas.getGraphics() // do your actions. Will give you big problem if you don't call dispose on the Graphics object after. On another note, calling: m圜anvas.getGraphics(). And the deprecated codes are not linked to Kawa version but to JDK version (The version of the java library used by Kawa). Check the option that talks about deprecated.
Look in Kawa settings, there should be some options for the compiler. You should do just what your compiler is telling you. It just means there are newer, better ways of doing it.

You are using at least one deprecated method: > // How big is the applet? > Dimension d = size() Use getSize instead of size.ĪutoCAD® and Excel – a match made in heaven? Well the drawing of a sine wave is just an arbitrary example of copy and pasting commands directly into the.
