How to determine which quadrant an angle lies in

The video tutorial explains how to determine the quadrant of an angle given in radians, specifically 3π/4. It begins with a review of the Cartesian coordinate system and the concept of quadrants. The instructor then explains radians, using the circle and π as references. The tutorial demonstrates how to calculate 3π/4 and identify its quadrant, which is Quadrant 2. The video concludes with a discussion on angles like 2π and their positions relative to the axes.

When graphing angles in standard form, which axis is used as the initial side?

• None of the above

• X-axis

• Z-axis

• Y-axis

How many radians are there in a full circle?

• π

• 2π

• 4π

• 3π

What is the angle measure of 3π/4 in terms of π?

• 1/2π

• 3/4π
