Can a radian be negative
WebNote 11 Negative Angles. On a number line, a positive number is measured to the right and a negative number is measured in the opposite direction (to the left). ... it is possible to convert between the two. Since one rotation around the unit circle equals 360 degrees or \(2\pi\) radians, we can use this as a conversion factor. WebAny angle given in radians can be converted to degrees using the steps given below, Note down the measure of the angle given in radians. We know, 1 radian = 180°/π. So, to …

WebThe definition of an angle that measures 1 radians is that the arc that subtends (lies across from) said angle has to measure 1 radius. If the arc length across from an angle is less than 1 radius long, then the angle is less than 1 radians. If the arc length is longer than 1 radius, than the angle is more than 1 radians. WebNegative angles rotate clockwise, so this means that $-\dfrac{\pi}{2}$ would rotate $\dfrac{\pi}{2}$ clockwise, ending up on the lower $y$-axis (or as you said, where $\dfrac{3\pi}{2}$ is located) .
