Dev C++ Arcsin
- Returns the principal value of the arc tangent of x, expressed in radians. In trigonometrics, arc tangent is the inverse operation of tangent. Notice that because of the sign ambiguity, the function cannot determine with certainty in which quadrant the angle falls only by its tangent value.
- Asin Parameters. The asin function takes a single mandatory argument in the range -1, 1. It is because the value of sine is in the range of 1 and -1.
- Jan 30, 2010 At arcsin(0.9) it loses 1 precision and at arcsin(1) it returns 77.5 (more or less). It seems to me that this algorithm requires more exactitude than the c types can give. Its quite easy to program this in c but for it to work (and it should) it requires more than the standard c library can offer.

Return Value
This function returns the arc sine of x, in the interval [-pi/2,+pi/2] radians.
Example
Sherlock holmes season 1 episodes. The following example shows the usage of asin() function.
Let us compile and run the above program that will produce the following result −
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.
