Evaluate the tangent inverse without a calculator

The video tutorial explains the concept of tangent inverse and its relation to coordinates. It discusses graphing points in different quadrants and explores angles and their restrictions using the unit circle. The tutorial also covers the use of coterminal angles to fit specific restrictions, providing a comprehensive understanding of these mathematical concepts.

Describe the significance of the restriction between π/2 and -π/2 in this context.
