#### Inverse Trigonometric Function: arccot

This LG covers the topic of inverse trigonometric, arc-cotangent function. It is an LG with a high number of tasks for two main reasons: (1) The cotangent function is not part of the secondary school mathematics program, so students in higher education learn the cotangent function and then its inverse function, so students have a greater difficulty, compared to other inverse trigonometric functions. (2) This is the last inverse trigonometric function studied, so this LG is intended to function a bit as a review of the topics covered, in the context of inverse trigonometric functions.
