I’ve added a new article with a video to the „Lectures” section (on the right sidebar) (click the link below):
It’s dedicated to cyclometric functions (arcsinx, arccosx, arctgx, arcctgx) and is divided into two parts. In the first part, I quickly show how to calculate them, and in the second part, I delve deeper into the topic (definitions, graphs).
Check it out, don’t waste your valuable points on cyclometric functions!

What are the definitions of arcsinx, arccosx, arctgx, and arcctgx?Telkom University Jakarta
Krystian Karczyński
The notations arcsinx, arccosx, arctgx, and arcctgx are just Polish ways of writing the inverse trigonometric functions sin⁻¹(x), cos⁻¹(x), tan⁻¹(x), and cot⁻¹(x). In Western countries, the notation sin⁻¹(x), cos⁻¹(x), etc. is more commonly used.
You can read more about inverse trigonometric functions here: Wikipedia – Inverse Trigonometric Functions.
