Hence, it is not the reference angle of the given angle. We just keep subtracting 360 from it until it’s below 360. If you're not sure of your work, you can draw the picture to be sure. This is easy to do. Let's check whether 2π/3 is. Counting reference angles in radians. The steps to calculate the reference angle are here: Radian measure and circular functions. 5 pi/3 is in the 4th quadrant so to find my reference angle i need to take 2 pi and subtract away my original angle. I made an animation showing how to “count” reference angles in radians.
The reference angle is the positive acute angle that can represent an angle of any measure.the reference angle must be <90∘. Subtract 180 180 from 240 240. Hence, it is not the reference angle of the given angle. But remembering the standard reference angles in radians is a bit more of a challenge. Let's check whether 2π/3 is. Substitute your angle into the equation to find the reference angle: If you tap into you basic counting nature, it gets easier. Now we would notice that it’s in the third quadrant, so we’d subtract 180° from it. Faq's on finding reference angle calculator. Identify the given angle {eq}\theta {/eq}. You just assign the positive or negative sign after determining a numerical value for the function from the reference angle.
