How do you know what quadrant a radian is in
WebA radian is a relative unit based on the circumference of a circle. As you know, radians are written as a fraction with a π, such as 2π/3, 5π/4, or 3π/2. Since the equation for the circumference of a circle is C=2πr, we have to keep the … WebAnytime you're plugging an angle into some equation. For example, 4 + 45degrees makes absolutely no sense because the units do not match. Notice that 45degrees = (pi/4). Now, …
