How To Find The Reference Angle In Radians and …

WebIn radian measure, the reference angle must be < π 2 . Basically, any angle on the x-y plane has a reference angle, which is always between 0 and 90 degrees. The reference angle is always the smallest angle that you can make from the terminal side of an angle (ie where the angle ends) with the x-axis. WebAnswer: At 2m, one steradian cuts through 2×2 = 4 m 2 of the sphere. And because the sensor is relatively small, its flat surface area is approximately the area of sphere that it occupies.
