Mastering the use of inverse trigonometric functions in integration is a key calculus skill. This involves understanding the derivatives of functions like sine, cosine, and tangent to simplify the integration process. Practical examples include integrating rational expressions with square roots and squares in the denominator, and direct integration of the functions themselves using methods like integration by parts.
