inverse trigonometric function

There are many notations used for the inverse trigonometric functions.

Luckily, these inverse trigonometric functions do not need to be computed.

Principal branches are also used in the definition of many inverse trigonometric functions.

These properties apply to all the inverse trigonometric functions.

Inverse trigonometric functions are found by reversing the process.

The following table describes the principal branch of each inverse trigonometric function:

To avoid confusion, an inverse trigonometric function is often indicated by the prefix "arc".

Just like the sine and cosine, the inverse trigonometric functions can also be defined in terms of infinite series.

Analogous formulas for the other functions can be found at Inverse trigonometric functions.

Calculus, including reduction formulae, surfaces of revolution and the inverse trigonometric functions.

Most standard mathematical functions (including the other inverse trigonometric functions) can be constructed using these.

Since the inverse trigonometric functions are analytic functions, they can be extended from the real line to the complex plane.

The inverse trigonometric functions can be used to calculate the internal angles for a right angled triangle with the length of any two sides.

I - Inverse trigonometric functions: arctan x, arcsec x, etc.

In computer programming languages the inverse trigonometric functions are usually called asin, acos, atan.

Expanding inverse trigonometric functions as power series is the easiest way to derive infinite series for π.

Inverse trigonometric functions:

Inverse trigonometric functions arcsine, arccosine and arctangent are quadrant-ambiguous, and results should be carefully evaluated.

It leads to inverse trigonometric functions first and usual trigonometric functions can be defined by inverting them back.

Inverse trigonometric functions are multiple-valued because trigonometric functions are periodic.

(See inverse trigonometric functions.)

However, this involves costly inverse trigonometric functions, which generally makes this algorithm slower than the ray casting algorithm.

Although sums, differences, and averages are easy to compute with high precision, even by hand, trigonometric functions and especially inverse trigonometric functions are not.

Later in the course, students are introduced to the law of cosines, sines, and tangents, as well as inverse trigonometric functions and problem solving related to trigonometry.

Finding the derivatives of the inverse trigonometric functions involves using implicit differentiation and the derivatives of regular trigonometric functions also given in the proofs section.
