The C library function double asin(double x) returns the arc sine of x in radians. Nov 29, 2016 Delphi is the ultimate IDE for creating cross-platform, natively compiled apps. Are you ready to design the best UIs of your life? Our award winning VCL framework for Windows and FireMonkey (FMX) visual framework for cross-platform UIs provide you with the foundation for intuitive, beautiful. Double asin (double x); float asin (float x); long double asin (long double x); double asin (T x); // additional overloads for integral types Compute arc sine Returns the principal value of the arc sine of x. 'arc' function is used to draw an arc with center (x, y) and stangle specifies starting angle, endangle specifies the end angle and last parameter specifies the radius of the arc. Arc function can also be used to draw a circle but for that starting angle and end angle should be 0 and 360 respectively. C programming source code for arc.
Trigonometric functions in C — and, indeed, in all programming languages — use radians, not degrees. What’s a radian? Glad you asked. A radian is a measurement of a circle, or, specifically, an arc. It uses the value ð (pi) instead of degrees, where ð is a handy circle measurement.
So instead of a circle having 360 degrees, it has 2ð radians. That works out to 6.2831 (which is 2 × 3.1415) radians in a circle.
For your trigonometric woes, one radian equals 57.2957795 degrees, and one degree equals 0.01745329 radians. So when you do your trig math, you need to translate between human degrees and C language radians.
CONVERT DEGREES TO RADIANS
Exercise 1: Type the source code from Convert Degrees to Radians into your editor. Line 10 is split so that it’s more readable on this page. You don’t need to split that line when you type it. Build and run. Test with the value 180, which should be equal to ð radians (3.14).
Exercise 2: Write a program that converts from radians to degrees.
Though C has many trigonometric functions, the three basic ones are sin(), cos(), and tan(), which calculate the sine, cosine, and tangent of an angle, respectively. Remember that those angles are measured in radians, not degrees.
Oh, and remember that you need the math.h header file to make the compiler happy about using the trig functions.

HAVING FUN WITH TRIGONOMETRY
Exercise 3: Type the source code from Having Fun with Trigonometry into your editor. Before you build and run, try to guess what the output could be.
Exercise 4: Modify the code from Having Fun with Trigonometry so that a cosine wave is displayed. Don’t get lazy on me! A cosine wave looks best when you cycle from 0 to 2ð. Modify your code so that you get a good, albeit character-based, representation of the curve.
No, Exercise 4 isn’t easy. You need to compensate for the negative cosine values when drawing the graph.

In the program (100, 100) are coordinates of center of arc, 0 is the starting angle, 135 is the end angle and radius of the arc is 50.
