👉 The term "sech" is a mathematical function that represents the hyperbolic secant, or cosecant of an angle in radians. Specifically, it's defined as:
\[ \text{sech}(\theta) = \frac{1}{\cos(\theta)} \]
where θ is the angle in radians.
This function has many applications in mathematics and physics, particularly when dealing with hyperbolic trigonometric functions. For example, sech can be used to find
