Find the reference angle and sketch both angles in standard position

The video tutorial explains how to find the reference angle for an angle in radians, specifically 7π/4. It begins by defining the reference angle and the terminal side in standard position. The instructor then demonstrates how to graph 7π/4 in standard form and identifies its position in the 4th quadrant. The reference angle is calculated using a formula, and the result is verified algebraically to ensure accuracy. The tutorial concludes with a confirmation that the reference angle is π/4.
