1. Introduction to Inverse Trigonometric Functions
Inverse trigonometric functions are the inverses of the standard trigonometric functions (sine, cosine, tangent, etc.). They are often denoted as arcsin, arccos, arctan, arccot, arcsec, and arccsc. These functions return the angle associated with a given trigonometric ratio, which is particularly useful in various mathematical applications.
Understanding these functions is essential for solving equations involving trigonometric identities and for integrating complex functions. The derivatives of these inverse functions are fundamental tools in calculus that help solve problems related to rates of change, optimization, and curve sketching.

The derivative of the arcsecant function is defined as:
f(x) = arcsec(x)
Then, the derivative is:
f'(x) = 1 / (|x| √(x² - 1)), for |x| > 1
2.6 Derivative of Arccosecant Function
The derivative of the arccosecant function is expressed as:
f(x) = arccsc(x)
Then, the derivative is:
f'(x) = -1 / (|x| √(x² - 1)), for |x| > 1
