"WebA correct version of the second fact would be that a radian has the same value (1) as the radius of the unit circle. The third fact states that one radian is equal to 57.3°. This is indeed true (albeit rounded). The circumference of a circle is 2π radius-lengths, so the angle of a complete circle is both 2π rad and 360°. Thus 1 rad = 180/π°. " - Explaining radians

WebTo convert 15.6358 degrees to deg min sec form do: Clearly we have 15 degrees, so the remaining 0.6358 is minutes and seconds. Since one degree has 60 min, we can write that x = 0.6358 * 60 So x is 38.148 min. A simpler example would be 0.5 degrees is equivalent to 0.5 * 60 = 30 minutes, so half of one degree, which makes sense. WebMar 26, 2016 · So the length of the bold arc is one-twelfth of the circle’s circumference. Because the bold arc is one-twelfth of that, its length is ð/6, which is the radian measure of the 30-degree angle. The unit circle’s circumference of 2ð makes it easy to remember that 360 degrees equals 2ð radians. Half the circumference has a length of ð, so ...
